PRODUCT BRIEF

Ultrasound Configurable Transmit Beamformer

General Description

Features

The LM96570 is an eight-channel monolithic beamformer for

pulse generators in multi-channel medical ultrasound appli-

cations. It is well-suited for use with National’s LM965XX

series chipset which offers a complete medical ultrasound

solution targeted towards low-power, portable systems.

Full control over selecting beam directions and pulse

patterns by programming individual channel parameters

■

Outputs interface seamlessly with positive and negative

inputs on octal high-voltage pulser ICs

Beamformer timing provides:

The LM96570 offers eight P and N output channels with indi-

vidual delays of up to 102.4 µs operating at pulse rates of up

to 80 MHz. A pulse sequence is launched on all channels si-

multaneously through a single firing signal. Advanced fea-

tures include delay resolution down to 0.78 ns and pro-

grammable patterns of up to 64 pulses. Pulse patterns and

delay settings are pre-programmed through a serial interface,

thereby simplifying the timing requirements on the driving cir-

cuitry.

Delay resolution of 0.78 ns

—

Delay range of up to 102.4 μs

Pulse patterns are locally generated with:

■

Sequences of up to 64 pulses

Adjustable Pulse widths

—

2.5V to 3.3V CMOS logic interface
