General Description

The HV7321 is a 4-channel, 5-level, ultrasound
transmitter with built-in T/R switches, output protection
diodes and clamp diodes. The HV7321 can provide up
to ±2.5A and the output voltage swing can be up to
±80V. The HV7321 supports both Transparent and
Re-Timing mode. The re-timing clock frequency can
support up to 220 MHz. The re-timing feature helps
reduce the output jitter introduced by the driving the
field-programmable gate array (FPGA). 
The HV7321 has two different modes for
CW transmission, CW-Mode 0 and CW-Mode 1. 
In CW-Mode 0 (Mode = 0, PWS = 0), the V

PP1

 and

V

NN1

 rails are used for CW transmission. The output

current is reduced in CW Mode-0.
In CW-Mode 1, the HV7321 accepts the output of an
external CW beamformer as CW source.
The HV7321 is LVCMOS 2.5V/3.3V input compatible,
which can be interfaced with the FPGA directly.
The HV7321 is available in a 9 mm x 9 mm 64-Lead
VQFN package.
