Chapter 1. Product Overview
1.1 INTRODUCTION
HV2903 Analog Switch Evaluation Board (ADM00795) works with HV MUX Controller
Board (ADM00825) to provide 32-Channel 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 circuit.
1.2 HV2903 IC - DESCRIPTION
The HV2903 is 32-Channel HV Analog Switches without HV Supplies. 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 in
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 switch ON/OFF operation and 3.3V for logic operation.
The HV2903 has two modes of operation: individual switching mode and bank switch-
ing mode. The user can select the mode by MODE pin logic input. The 32 analog
switches can be controlled individually through digital interface when 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
logic inputs when MODE input is low (bank switching mode).
The HV2903 has standby mode to decrease power consumption at idle state. When
STBY logic input is low, it operates in standby mode and consumes very low current.
When STBY logic input is high, it operates normally.
1.3 HV2903 ANALOG SWITCH EVALUATION BOARD - FEATURES
• One HV2903 32-Channel HV Analog Switches without HV Supplies
• Designed to work with Microchip HV MUX Controller Board

Chapter 3. PCB Design and Layout Notes
3.1 PCB LAYOUT TECHNIQUES FOR HV2903
The HV2903 is 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.
3.1.1 High-Voltage & 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 (VSUB). 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
50to 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 PCB layout. The
internal circuitry of the HV2903 can operate at quite 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 feed-through 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 to prevent resonance in the power sup-
ply 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 cir-
culating ground return current from a capacitive load cannot react with common induc-
tance to create noise voltages in the input logic circuitry.
3.1.2 Decoupling Capacitors Selection
The VLL, VDD and VSS 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-mounted ceramic capacitor of 1.0 to 2.2 μF 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 pur-
poses.
