The HV7322 is an 8-channel, true 5-level or pseudo 7-level high-voltage pulser with integrated transmit/receive switches, designed for medical ultrasound and nondestructive testing applications. It supports output voltages up to ±80V and peak output currents of ±2A, with programmable output levels of ±0.5A, ±1.0A, ±1.5A, and ±2.0A. The device features a 220MHz differential clock retiming input to synchronize logic signals and reduce jitter from FPGA timing inaccuracies. Each channel includes integrated 13Ω T/R and low-voltage switches, 160Ω return-to-zero switches for true zero voltage, and RF blocking with clamp diodes. The 206-lead TFBGA package measures 12mm x 12mm x 1.20mm. Logic control inputs are compatible with 2.5V and 3.3V LVCMOS signals.
The HV7322 is an 8-channel, true 5-Level or pseudo 7-Level, high voltage pulser with integrated dual T/R switches. It is designed for medical ultrasound or nondestructive testing (NDT) applications.
The device has seven output levels: VPP0, 1, 2, VNN0, 1, 2 and GND. The output transistors can provide up to ±2A of current at ±80V maximum.
HV7322 has the 220 MHz differential retiming clock which realigns the logic input signals to a master clock. This feature reduces delay variations caused by FPGA inaccuracies and/or long PCB traces.
The built-in gate driver regulators allow interdependent VPP0, 1, 2 and VNN0, 1, 2 HV rails and freely move the voltage from 0 to ± 80V.
The logic control voltages are designed to work with LVDS or LVCMOS logic families.
