General Description

The HV7351 device is an 8-channel, programmable

high-voltage ultrasound-transmit beamformer. Each

channel is capable of swinging up to ±70V with an

active discharge back to 0V. The outputs can source

and sink up to 3.0A to achieve fast output rise and fall

times. The active discharge is also capable of sourcing

and sinking 3.0A for a fast return to ground. The topol-

ogy of the HV7351 will significantly reduce the number

of I/O logic control lines needed.

Each pulser has four associated 64-bit Shift registers

for storing predetermined transmit patterns and a 10-bit

delay counter for controlling the transmit time. One of

four arbitrary patterns can be transmitted with adjust-

able delay, depending on the data loaded into these

Shift registers and the delay counter. The delay counter

can be clocked up to 200 MHz, allowing incremental

delays down to 5 ns.
