Device Overview

Summary

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 a driving 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 the CW source. The HV7321 is LVCMOS 2.5V/3.3V input compatible, which can interface directly with an FPGA.  The HV7321 is available in a 9 mm x 9 mm 64-Lead VQFN package.
