Chapter 1. Product Overview

1.1 INTRODUCTION

HV2903 Analog Switch Evaluation Board (ADM00795) works with HV MUX Controller Board (ADM00825) to provide 32-channel, high-voltage (HV) analog switches, without HV supplies demonstration, including basic switch ON/OFF operation and 2:1 MUX operation, with two built-in MD1822 and TC6320 pulser circuits.

1.2 HV2903 INTEGRATED CIRCUIT - DESCRIPTION

The HV2903 device is a no HV bias, low-harmonic distortion, low-charge injection, consisting of 32-channel, HV analog switches. It is designed for use in applications requiring high-voltage switching controlled by low-voltage control signals, such as medical ultrasound imaging, driving piezoelectric transducers and printers. The typical 10Ω on resistance analog switch can pass the analog pulse signal up to ±3A of current at ±100V, without high-voltage supplies such as ±100V. It requires only ±6V or ±5V for the ON/OFF switch operation and 3.3V for logic operation.

The HV2903 device has two modes of operation: Individual Switching mode and Bank Switching mode. The user can select the mode with the MODE pin logic input. The 32 analog switches can be controlled individually through a digital interface when the MODE input is high (Individual Switching mode). The digital interface clock operates up to 66 MHz. All 16 even switches and all 16 odd switches can be controlled together through simple 2-input logic when the MODE input is low (Bank Switching mode).

The Standby mode is used to decrease power consumption during idle state. When STBY logic input is low, the HV2903 device operates in Standby mode and consumes very low current. When STBY logic input is high, the device operates normally.

1.4 HV2903 ANALOG SWITCH EVALUATION BOARD – FUNCTIONAL DESCRIPTION

The HV2903 Analog Switch Evaluation Board can control the HV2903 operation and built-in pulsers that are connected to two 2:1 MUX switches for demonstration. Four switch outputs of two 2:1 MUX have SMA connectors and the user can connect four transducer elements. The other side of the 2:1 MUX is connected to two built-in MD1822 and TC6320 pulsers. The HV2903 Analog Switch Evaluation Board can drive four transducer elements with 5 MHz, ±100V pulse signals.

The evaluation board features one HV2903/AHA 12x12x1.2 mm 132-Lead TFBGA packaged integrated circuit, two MD1822K6-G 3x3x1 mm 16-Lead QFN packaged integrated circuits, and four TC6320K6-G 4x4x1 mm 8-Lead DFN packaged NMOS and PMOS pair integrated circuits.

The HV2903 Analog Switch Evaluation Board uses two high-speed 20-signal pair carrying-capable, right-angle backplane connectors, which are designed to work with the Microchip HV MUX Controller Board (ADM00825) 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 means of a Microsoft® Windows® driver and GUI, the user can control the HV2903 device and two built-in pulsers.

Four switch terminals, consisting of two MUX configurations on the PCB, have SMA connectors to which the user can connect loads. Jumpers close to SMA connectors are for connecting the on-board dummy R-C load (330 pF//2.5 kΩ) optionally to the pulser output.

WARNING

Chapter 3. PCB Design and Layout Notes

3.1 PCB LAYOUT TECHNIQUES FOR HV2903

The HV2903 Evaluation Board is equipped with a HV2903 device, which has 32 analog switches and is able to pass high-voltage, high-current and high-frequency pulses. The PCB design and layout of the board are important to ensure the success of the implementation.

3.1.1 High-Voltage and High-Speed Grounding, and Layout Techniques

The center balls at the bottom of the HV2903 TFBGA package are internally connected to the IC's substrate ( V_SUB ). These balls should be connected to GND, externally on the PCB.

The designer must pay attention to the connecting traces, since the analog switches pass the high-voltage and high-speed signals. In particular, controlled impedance of 50Ω 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 HV2903 Analog Switch Evaluation Board PCB layout. The internal circuitry of the HV2903 can operate at a high frequency, with the primary speed limitation being the load capacitance. Because of this high speed and the 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 feedthrough via connections that are connected directly to a solid ground plane at the second layer of the PCB.

It is advisable to minimize the trace length to the ground plane, and to insert a ferrite bead in the power supply lead to the capacitor, in order to prevent resonance in the power supply lines.

Pay particular attention to minimizing trace lengths and using 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 will prevent any possible parasitic capacitance coupling. The user should also ensure that the circulating ground return current from a capacitive load cannot react with common inductance to create noise voltages in the input logic circuitry.

3.1.2 Decoupling Capacitors Selection

The V_LL , V_DD and V_SS supply voltage rails can provide fast transient current. Therefore, they should have a low-impedance bypass capacitor at each of the chip's pins. Use a surface mount ceramic capacitor of 1.0 to 2.2 F capacitance with an appropriate voltage rating.

The user needs to pay additional attention to 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.
