USB-C™ to DisplayPort Active Cable Reference Design

(1) This design sources power from both VCONN and VBUS, slight modification must be made to be source power from Vconn only.

1 System DescriptionThe USB-C™ DP Active Cable reference design is a framework that can enable DisplayPort videosignaling over a USB-C™ connection. This design features DisplayPort video transfers over DisplayPortCables, up to 5 meters in length, over a single USB-C™ cable connection. This enables DisplayPortcommunication between legacy DisplyPort sink to new USB-C™ source that have Displaypotyfunctionality. USB-C™ to DisplyPort cables are typically passive and are therefore bi-directional but thesepassive cables are typically short (1m to 2m). In order to extend cable length, a passive cable must bemade active through use of a signal conditioner. This reference design enables an active bi-directionalUSB-C™ to DisplyPort cable/converter for USB-C™ alternative mode applications.

2 System Overview

2.1 Block Diagram

Figure 1. TIDA-01620 Block Diagram

2.2 Design ConsiderationsThis USB-C™ to DisplyPort Active Cable design is created to be compliant to VESA DisplayPort Alt Modespecification. Several key considerations must be taken into account when considering designs thatenable USB-C™ with DisplayPort Alt Mode. Designs of this nature should:• Use minimal power (<1 W) such that power can be completely sourced from USB-C™ VCONN pin (1).• Present a USB Billboard in order to notify USB host of ALT Mode capability.• Support both pin assignment C and E as specified by VESA DisplayPort Alt Mode specification.

These features should be implemented in USB-C™ to DisplyPort designs in order to be compliant withVESA DisplayPort Alt Mode specification. For complete details on the considerations above, refer to"VESA DisplayPort Alt Mode on USB Type-C Standard (DisplayPort Alt Mode)" specification.

2.3.3 TPS63051: Single Inductor Buck-Boost With 1-A Switches and Adjustable Soft StartThe TPS63051 family of devices is a high efficiency, low quiescent-current buck-boost converter, suitablefor applications where the input voltage is higher or lower than the output. Continuous output current cango as high as 500 mA in boost mode and as high as 1 A in buck mode. The maximum average current inthe switches is limited to a typical value of 1 A. The TPS63051 regulates the output voltage over thecomplete input voltage range by automatically switching between buck or boost mode depending on theinput voltage, ensuring seamless transition between modes.

The buck-boost converter is based on a fixed-frequency, pulse-width-modulation (PWM) controller usingsynchronous rectification to obtain the highest efficiency. At low load currents, the converter enters PowerSave Mode to maintain high efficiency over the complete load current range.

2.3.4 MSP430F5528: Mixed-Signal Micro-controllersThe TI MSP430™ family of ultra-low-power micro-controllers consists of several devices featuringperipheral sets targeted for a variety of applications. The architecture, combined with extensive low-powermodes, is optimized to achieve extended battery life in portable measurement applications. The micro-controller features a powerful 16-bit RISC CPU, 16-bit registers, and constant generators that contribute tomaximum code efficiency. The digitally controlled oscillator (DCO) allows the devices to wake up from low-power modes to active mode in 3.5 µs (typical).

The MSP430F5528 micro-controller has integrated USB and PHY supporting USB 2.0, four 16-bit timers,a high-performance 12-bit analog-to-digital converter (ADC), two universal serial communication interfaces(USCI), a hardware multiplier, DMA, a real-time clock (RTC) module with alarm capabilities, and 47 I/Opins.

Each device can dissipate ESD strikesabove the maximum level specified by the IEC 61000-4-2 international standard. The TPD4E05U06 ultra-low loading capacitance makes it ideal for protecting any high-speed signal pins. Typical applications forTPD4E05U06 includes high speed signal lines in USB 3.0 and DisplayPort.

2.3.6 TPD4E02B04: 4-Channel ESD Protection Diode for USB Type-C and HDMI 2.0The TPD4E02B04 is a bidirectional TVS ESD protection diode array for USB Type-C and HDMI 2.0 circuitprotection. The TPD4E02B04 is rated to dissipate ESD strikes at the maximum level specified in the IEC61000-4-2 international standard (Level 4). This device features a 0.25-pF IO capacitance per channelmaking it ideal for protecting high-speed interfaces up to 10 Gbps such as USB 3.1 Gen2. The lowdynamic resistance and low clamping voltage ensure system level protection against transient events.

Figure 7. TPD4E02B04 Functional Block Diagram

2.3.7 ESD122: 2-Channel ESD Protection Diode for USB Type-C and HDMI 2.0The ESD122 is a bidirectional TVS ESD protection diode array for USB Type-C and HDMI 2.0 circuitprotection. The ESD122 is rated to dissipate contact ESD strikes at the maximum level specified in theIEC 61000-4-2 international standard (17-kV Contact, 17-kV Air-gap). This device features a low IOcapacitance per channel and pin-out to suit symmetric differential high-speed signal routing making it idealfor protecting high-speed interfaces up to 10 Gbps such as USB 3.1 Gen2.

The ESD122 is an ideal ESD solution for the USB Type-C Tx/Rx lines. Since the USB Type-C connectorhas two layers, using 4- channel ESD devices require VIAs which degrade the signal integrity. Using fourESD122 (2-Ch) devices minimize the number of VIAs and simply the PCB board layout.
