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 VPP1 and

VNN1 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.
