1 TUSB9260 Typical System Implementation
Figure 1 represents a typical implementation of the TUSB9260 USB 3.0 to Serial ATA Bridge. The deviceserves as a bridge between a downstream USB 3.0 host port and a SATA device such as a hard diskdrive. A crystal or oscillator supplies the required clock source. A SPI Flash device contains the firmwarethat is loaded into the TUSB9260 after the de-assertion of RESET. Push buttons or any other desired logiccan be connected to the TUSB9260 GPIO terminals. The TUSB9260 can also output a pulse widthmodulated signal that can be used to drive an activity LED.

Power Considerations www.ti.com
2 Power Considerations
2.1 1.1-V and 3.3-V Digital Supplies
The TUSB9260 requires 1.1-V and 3.3-V digital power source.
The 1.1-V terminals are named VDD11. These terminals supply power to the digital core. The 1.1- V coreallows for a significant reduction in both power consumption and logic switching noise.
The 3.3-V terminals are named VDD33 and supply power to most of the input and output cells.
Both VDD11 and VDD33 supplies must have 0.1-µF bypass capacitors to VSS (ground) to ensure properoperation. One capacitor per power terminal is sufficient and should be placed as close to the terminal aspossible to minimize trace length. Smaller value capacitors like 0.01-µF are also recommended on thedigital supply terminals.
When placing and connecting all bypass capacitors, high-speed board design rules must be followed.
2.2 1.1-V, 1.8-V and 3.3-V Analog Supplies
A Pi filter is recommended on all analog power terminals to minimize circuit noise. These filters can becombined on a per-rail basis for a total of three (VDDA11/VDDA11_USB2) + (VDDA18/VDDR18) +(VDDA33).
Analog power terminals must have a 1-µF and a 10-µF bypass capacitor connected to VSSA (ground) toensure proper operation. Place the capacitor as close as possible to the associated terminal to minimizetrace length. Smaller value capacitors such as 0.1-µF and 0.01-µF are also recommended on the analogsupply terminals.
2.3 Ground Terminals
VSS, VSSA, VSS18, and VSS33 can be connected together to form one ground plane. This techniqueallows for creating a large image plane for the signal layer directly adjacent to the ground plane.
2.4 Capacitor Selection Recommendations
When selecting bypass capacitors for the TUSB9260 device, X7R-type capacitors are recommended. Thefrequency versus impedance curves, quality, stability, and low-cost of these capacitors make them alogical choice for most computer systems.
The selection of bulk capacitors with low-ESR specifications is recommended to minimize low-frequencypower supply noise. Today, the best low-ESR bulk capacitors are radial leaded aluminum electrolyticcapacitors. These capacitors typically have ESR specifications that are less than 0.01 Ω at 100 kHz. Also,several manufacturers sell “D” size surface mount specialty polymer solid aluminum electrolytic capacitorswith ESR specifications slightly higher than 0.01 Ω at 100 kHz. Both of these bulk capacitor optionssignificantly reduce low-frequency power supply noise and ripple.
2.5 Power-Up/Down Sequencing
All TUSB9260 analog and digital power terminals must be controlled during the power-up and power-downsequence to ensure that absolute power terminal ratings are not exceeded as doing so can result indamage to the device.
No particular power-up or power-down sequencing of the power rails is required.
For additional power requirements, please refer to the TUSB9260 Data Manual (SLLS962).

www.ti.com USB Connection
2.6 External Voltage Regulator Recommendation
Since the TUSB9260 requires three voltage supplies (1.1-V, 1.8-V, and 3.3-V) a multi-channel voltageregulator is recommended. The TPS650061 or TPS65024x are good choices. The TPS650061 utilizes aDCDC converter and two LDO regulators in a single package. The DCDC converter can supply 1-Anominal current while the two LDO’s can supply 300-mA nominal current. Since the 1.1-V supply canconsume upwards of 340-mA of current the DCDC converter is ideal for supplying the 1.1-V current whilethe two LDO’s can be used to supply 1.8-V and 3.3- V current. Likewise the TPS65024x utilizes threeDCDC converters and three LDO’s. Both devices also have a built in supervisor circuit that can beconnected to GRST# on the TUSB9260.
2.7 TUSB9260 Power Consumption
Nominal power ratings for the TUSB9260 are shown in Table 1. Measurements were taken at nominalvoltage while transferring data via USB3 to a SSD drive.
Table 1. TUSB9260 Nominal Power Consumption by Voltage Rail (Approximate)
VOLTAGE RAIL CURRENT POWER
3.3 V 6 mA 19.8 mW
1.8 V 58 mA 104.4 mW
1.1 V 319 mA 350.9 mW
Total 383 mA 475.1 mW
2.8 USB VBUS
Power can be supplied via a USB cable on the terminal VBUS. VBUS is a 5-V source that is connected tothe USB_VBUS terminal on the TUSB9260 via a voltage divider. Connect a 90.9-kΩ, 1% resistor from thecable VBUS connector to the USB_VBUS terminal on the TUSB9260 and a 10-kΩ, 1% resistor fromUSB_VBUS to ground.
2.8.1 Limiting Inrush Current on VBUS
To prevent inrush current the TI TPS2560/61 is recommended. Inrush current can occur on VBUS when afunction is plugged into the network. For example the bulk capacitance used to supply power to the SATAdevice can be quite large, causing inrush current when the USB cable is connected. The TPS2560/61power-distribution switches are intended for applications where heavy capacitive loads are likely to beencountered. The TPS2560/61 has two controllable outputs that can be controlled via the TUSB9260GPIO terminals. In the example implementation the TUSB9260 is used to switch power on or off to theSATA device by controlling the EN2 terminal on the TPS2561.
3 USB Connection
There are three sets of differential pairs for connecting the USB port; one set for High-Speed and two setsfor SuperSpeed.
3.1 High-Speed Differential Routing
The high-speed differential pair (USB_DM and USB_DP) is connected to a USB type B connector. Thedifferential pair traces should be routed with 90-Ω, ±15% differential impedance. The high-speed signalpair should be trace length matched. Maximum trace length mismatch between High-Speed USB signalpairs should be no greater than 150 mils. Keep total trace length to a minimum. Route differential tracesfirst. Route the differential pairs on the top or bottom layers with the minimum amount of vias possible. Notermination or coupling caps are required. If a common mode choke is required then place the choke asclose as possible to the USB connector signal pins. Likewise ESD clamps should also be placed as closeas possible to the USB connector signal pins (closer than the choke).
In order to minimize cross-talk on the USB2/3 differential signal pairs, it is recommended that the spacingbetween the two interfaces be five times the width of the trace (5W rule). For instance, if the SS USBTX/RX differential pair trace widths are 5 mils, then there should be 25 mils of space (air gap) between theTX and RX differential pairs and the DP/DM differential pair.

SATA Connection www.ti.com
If this 5W rule cannot be implemented, then the space between the TX/RX differential pairs and DP/DMdifferential pairs should be maximized as much as possible and ground-fill should be placed between thetwo. In this case, it is better to route each differential pair on opposite sides of the board with a groundplane between them.
3.2 SuperSpeed Differential Routing
SuperSpeed consists of two differential routing pairs, a transmit pair (USB_SSTXM and USB_SSTXP) anda receive pair (USB_SSRXM and USB_SSRXP). Each differential pair’s traces should be routed with90-Ω, ±15% differential impedance. The high-speed signal pair should be trace length matched. Maximumtrace length mismatch between SuperSpeed USB signal pairs should be no greater than 2.5 mils. Thetransmit differential pair does not have to be the same length as the receive differential pair. Keep totaltrace length to a minimum. Route differential traces first. Route the differential pairs on the top or bottomlayers with the minimum amount of vias possible. The transmitter differential pair requires 0.1-µF couplingcaps for proper operation. The package/case size of these caps should be no bigger than 0402. C-packsare not allowed. The caps should be placed symmetrically as close as possible to the USB connectorsignal pins. If a common mode choke is required then place the choke as close as possible to the USBconnector signal pins (closer than the transmitter caps). Likewise ESD clamps should also be placed asclose as possible to the USB connector signal pins (closer than the choke and transmitter caps).
It is permissible to swap the plus and minus on either or both of the SuperSpeed differential pairs. Thismay be necessary to prevent the differential traces from crossing over one another. However it is notpermissible to swap the transmitter differential pair with receive differential pair.
In order to minimize cross-talk on the SS USB differential signal pairs, it is recommended that the spacingbetween the TX and RX signal pairs be five times the width of the trace (5W rule). For instance, if the SSUSB TX/RX differential pair trace widths are 5 mils, then there should be 25 mils of space (air gap)between the TX and RX differential pairs.
If this 5W rule cannot be implemented, then the space between the TX and RX differential pairs should bemaximized as much as possible and ground-fill should be placed between the two. In this case, it is betterto route each differential pair on opposite sides of the board with a ground plane between them.
4 SATA Connection
The TUSB9260 supports one 3G SATA port operating at 1.5 GHz or 3 GHz depending on the maximumspeed of the attached device.
4.1 SATA Differential Routing
The SATA traces (SATA_TXP and SATA_TXM) should be routed with 100-Ω, ±15% differentialimpedance. Maximum trace length mismatch between SATA signal pairs should be no greater than2.5 mils. Transmit differential pair does not have to be the same length as receive differential pair. Keeptotal trace length to a minimum. Route differential traces first. Route the differential pairs on the top orbottom layers with the minimum amount of vias possible. Each SATA trace requires a coupling capacitorbe placed inline. The package/case size of these caps should be no bigger than 0402. C-packs are notallowed. The caps should be placed symmetrically as close as possible to the SATA connector signalpins.
It is permissible to swap the plus and minus on the SATA differential pair. This may be necessary toprevent the differential traces from crossing over one another. However it is not permissible to swap thetransmitter diff pair with the receive diff pair.
In order to minimize cross-talk on the SATA differential signal pairs, it is recommended that the spacingbetween the TX and RX signal pairs for each interface be five times the width of the trace (5W rule). Forinstance, if the SATA TX/RX differential pair trace widths are 5 mils, then there should be 25 mils of space(air gap) between the TX and RX differential pairs.
If this 5W rule cannot be implemented, then the space between the TX and RX differential pairs should bemaximized as much as possible and ground-fill should be placed between the two. In this case, it is betterto route each differential pair on opposite sides of the board with a ground plane between them.

5 ESD Protection
The TUSB9260 provides ESD protection on all signal and power pins up to 2000 V using the human bodymodel and 500 V using the charged device model. If more protection is required, the TI TPD2EUB30 canbe used as this device meets or exceeds IEC61000-4-2 (Level 4) requirements. This device can be usedon any of the differential pairs of the TUSB9260. Place the device as close as possible to the signal pinsof the connector. Refer to the datasheet for more information regarding this device.
6 GPIO Terminals
The TUSB9260 supports a minimum of 12 GPIOs. Some GPIO terminals have dual functionalitydepending on how they are configured.
6.1 GPIO[7:0]
GPIO terminals 7 through 0 can be used for general purpose use such as connecting activity LEDs, usedas push-button input, or connected to various signals from other devices. Each GPIO terminal has internalpull-down resistors. If a GPIO terminal is not used it should be left unconnected.
6.2 GPIO[8/UART_RX:9/UART_TX]
GPIO terminals 8 and 9 are dual function terminals. They can be used as general purpose input/outputterminals like GPIO[7:0] or they can be configured as an UART interface. Both terminals have internalpull-up resistors, so they can be left unconnected if not used.
6.3 GPIO[10/SPI_CS2:11/SPI_CS1]
GPIO terminals 10 and 11 are dual function terminals. They can be used as general purpose input/outputterminals like GPIO[7:0] or they can be configured as SPI chip select terminals for additional peripheralssuch as an LCD driver. Both terminals have internal pull-up resistors, so they should be left unconnected ifnot used.
7 PWM Terminals
The TUSB9260 has two pulse width modulated (PWM) terminals. These terminals are always outputs.They should be left unconnected if not used.
8 JTAG Interface
The TUSB9260 supports JTAG for board level test and debug support. Typically these terminals are leftunconnected or routed to a header to plug in an external JTAG controller. Table 2 shows the JTAGterminal names and internal resistor connection. The JTAG interface should be left unconnected if JTAGsupport is not required.

9.2 External Clock/Oscillator Selection
When using an external clock source such as an oscillator, the reference clock should have ±100 PPM (orbetter) frequency stability and have less than 50-ps absolute peak to peak jitter or less than 25-ps peak topeak jitter after applying the USB 3.0 jitter transfer function.
Connect the output of the clock source or oscillator to the XI terminal. Leave the XO terminal unconnectedas shown in Figure 4. Try to keep the clock trace to a minimum length with few or no vias.
Note that the TUSB9260 has a VSSOSC terminal. This terminal is the reference ground for the internaloscillator. This reference ground should be used for the crystal circuit, which is also shown in Figure 4.

Serial Peripheral Interface (SPI) www.ti.com
Figure 4. Example Oscillator Implementation
10 Serial Peripheral Interface (SPI)
A SPI system consists of one master device and one or more slave devices. The TUSB9260 is a SPImaster providing the SPI clock, data-in, data-out and up to three chip select terminals.
The SPI has a 4-wire synchronous serial interface. Data communication is enabled with a low active ChipSelect terminal (SPI_CS[2:0]#). Data is transmitted with a 3-terminal interface consisting of terminals forserial data input (SPI_DATA_IN), serial data output (SPI_DATA_OUT) and serial clock (SPI_SCLK). AllSPI terminals have integrated pull-up resistors. No external components are required to connect the SPIinterface to an external SPI flash device. See Figure 5 for an example implementation of the SPI interfaceusing one SPI slave device.
Figure 5. SPI Connection
The SPI interface can operate over a frequency range of 100 kHz to 50 MHz. The word size for the flashmust be 8 bits. A minimum flash size of 512 kbits (64 k x 8) is recommended. Table 4 shows SPI flashdevices that have been tested with the TUSB9260.

11 Precision Reference Return Resistor
The TUSB9260 requires an external precision reference return resistor. This resistor is part of the USB2.0PHY core used for internal calibration. A 10-kΩ, ±1% (1/20 W or greater) precision resistor should beplaced between terminals USB_R1 and USB_R1RTN. This resistor should be placed no further than500 mils from the two terminals.
12 External PLL Loop Capacitors
There are three terminals on the TUSB9260 that require external capacitors. These are the external loopcapacitors for each of the three PLL’s in the TUSB9260. CEXT0 terminal is used for the USB 2.0 PHYPLL, CEXT1 terminal is used for the SuperSpeed PHY PLL, and terminal CEXT2 is used for the SATAPLL.
All three CEXTx terminals require a 4.7-nF capacitor connected to ground. Each capacitor should beplaced within 500 mils of its associated terminal and provide adequate shielding from external noisesources.
13 Example Schematics
The following schematic is provided as a reference design. There is one user configurable jumper (J4) onthe board. A jumper must be placed across pins 1 and 2 or across pins 2 and 3 depending on the desiredpower option. When the jumper is placed across pins 1 and 2 a flash drive can be powered directly fromthe USB cable power eliminating the need for an external wall-wart. However it should be noted that SATAdevices that require 12 V will not operate in this mode. To support all SATA devices place the jumperacross pins 2 and 3 and connect a 12-V / 2-A wall-wart to DC jack J3 (positive tip).
