HV2918 ANALOG SWITCH EVALUATION BOARD
USER’S GUIDE
Chapter 1. Product Overview
1.1 INTRODUCTIONThe HV2918 Analog Switch Evaluation Board (EV19W62A) works with the Microchip HV MUX Controller Board (ADM00825) to provide no high-voltage bias, low harmonic distortion, 32-channel, high-voltage analog switch demonstration, including basic switch on/off operation. The boards also include 2:1 MUX operation to transmit ±100V high-voltage pulse burst from two built-in MD1822 and TC6320 pulser circuits.
1.2 HV2918 DEVICE SHORT OVERVIEWThe HV2918 device is a no high-voltage bias, low harmonic distortion, 32-channel (16 2:1 MUX), high-voltage analog switch (with bleed resistors in SW pins). It is designed to be used in applications requiring high-voltage switching, controlled by low-voltage control signals, such as medical ultrasound imaging, driving piezoelectric transducers and in printers. The typical 6 on-resistance analog switch can pass the analog pulsed signal up to ±2.7A of current, ±100V of voltage and 2.5 µs of pulse width without high-voltage supplies, such as ±100V. It requires only a +5V single bias voltage supply of VDD and VLL for the on/off switch operation. The user can also use +3.3V instead of +5V in the Logic Voltage, VLL, in order to get lower power consumption.The HV2918 device has a digital serial interface to control the 32 analog switches individually. The digital interface clock operates up to 66 MHz.HV2918 has an asymmetric topology to implement small size, compared to other no high-voltage bias analog switch products. In the asymmetric topology, the SW pin can pass a high-voltage pulsed signal, applied to the Y pin, when the switch is in the ON state. When the switch is in the OFF state, high voltage should not be applied to the SW pin. In medical ultrasound systems, the Y pin is connected to Tx/Rx and the SW pin is connected to a single piezoelectric transducer element in order to avoid high-voltage at the SW pin during the switch OFF state.
1.3 HV2918 ANALOG SWITCH EVALUATION BOARD FEATURES• HV2918 No High-Voltage Bias, Low Harmonic Distortion, 32-Channel,
(16 2:1 MUX), High-Voltage Analog Switch (with Bleed Resistors in SW Pins)• Designed to work with the Microchip HV MUX Controller Board (ADM00825)• Two 2:1 MUX with built-in MD1822 and TC6320 Pulsers• 5 MHz 3-Level High-Voltage Pulse Burst Outputs• On-Board 330 pF//2.5 k Dummy Load per SW6, SW7, SW24, SW25 Pins• Pulser On/Off and Time Domain Control through the PC GUI and the HV MUX

HV2918 Analog Switch Evaluation Board User’s Guide
1.4 WHAT IS THE HV2918 ANALOG SWITCH EVALUATION BOARD?The HV2918 Analog Switch Evaluation Board can control the HV2918 device and built-in pulsers that are connected to the two 2:1 MUX switches for demonstration through the HV MUX Controller Board and GUI. Four switch outputs (SW pins) from two 2:1 MUXes have SMA connectors to which the user can connect four transducer elements. The other side of the 2:1 MUX (Y pins) is connected to the outputs of two built-in MD1822 and TC6320 pulsers. The HV2918 Analog Switch Evaluation Board can drive four transducer elements with 5 MHz, ±100V pulse signals.The HV2918 Analog Switch Evaluation Board features one HV2918/R4X 9 x 9 x 0.9 mm 64-lead VQFN packaged integrated circuit, two MD1822K6-G 3 x 3 x 1 mm 16-lead QFN packaged integrated circuits and four TC6320K6-G 4 x 4 x 1 mm 8-lead DFN packaged NMOS and PMOS paired integrated circuits.The HV2918 Analog Switch Evaluation Board uses two high-speed 20-signal pairs, carrying capable right angle backplane connectors, which are designed to work with the HV MUX Controller Board as a control signal source.The HV MUX Controller Board has an FPGA that generates pulser waveform and logic control signals, and a USB bridge IC that connects the control board to a PC. By using a Microsoft® Windows® operated PC and the GUI software, the user can control the HV2918 device and two built-in pulsers on the HV2918 Analog Switch Evaluation Board.Four switch terminals, consisting of two 2:1 MUX configurations on the PCB, have SMA connectors to which the user can connect loads. The jumpers close to the SMA con-nectors are for connecting the on-board dummy R-C load (330 pF//2.5 k) optionally to the pulser output.

Chapter 4. PCB Design and Layout Notes
4.1 PCB LAYOUT TECHNIQUES FOR HV2918The HV2918 Analog Switch Evaluation Board has an analog switch to pass high- voltage, high-current and high-frequency pulses. The PCB design and layout are important to ensure the success of the implementation.
4.1.1 High-Voltage and High-Speed Grounding and Layout Techniques
The center pad at the bottom of the HV2918 VQFN package is internally connected to the IC’s substrate (VSUB). This pad should be connected to GND, externally on the PCB.The user must pay attention to the connecting traces, since the analog switches pass the high-voltage and high-speed signals. In particular, a controlled impedance of 50 to the ground plane and more trace spacing needs to be applied in this situation.High-speed PCB trace design practices are used for the HV2918 Analog Switch Eval-uation Board PCB layout. The internal circuitry of the HV2918 device can operate at a high frequency, with the primary speed limitation being the load capacitance. Because of these high-speed and high-transient currents that result from driving capacitive loads, the supply voltage bypass capacitors should be as close to the pins as possible. All the GND pins should have low-inductance feed through connections that are connected directly to a solid ground plane at the second layer of the PCB. It is recom-mended to minimize the trace length to the ground plane and to insert a ferrite bead in the power supply lead to the capacitor to prevent resonance in the power supply lines. It is important to minimize trace lengths and use sufficient trace width to reduce inductance. Surface mount components are highly recommended.The use of a solid ground plane, and good power and signal layout practices prevent any possible parasitic capacitance coupling. The user should also ensure that the circulating ground return current from a capacitive load does not react with common inductance to create noise voltages in the input logic circuitry.
4.1.2 Decoupling Capacitors SelectionThe VLL and VDD supply voltage rails are able to provide fast transient current. There-fore, they should have a low-impedance bypass capacitor close to each of the power supply pins. Use a surface-mounted ceramic capacitor of 0.1 to 2.2 µF capacitance with an appropriate voltage rating.It is important to verify what type of ceramic capacitor is selected for these bypass capacitors. The low-impedance means low-ESR/ESL impedance within the frequency bandwidth range of ultrasound pulses transmitted, including the very fast dV/dt of the pulse’s rising and falling edges. A capacitor with low-temperature coefficient and low-voltage coefficient is also recommended. The type of X7R and X5R or other more advanced multilayer ceramic types should be selected for these purposes.
