描述 Description

The LM96570 is an eight-channel monolithic beamformer for pulse generators in multi-channel medical ultrasound applications. It is well-suited for use with the LM965XX series chipset which offers a complete medical ultrasound solution targeted towards low-power, portable systems.

The LM96570 offers eight P and N output channels with individual delays of up to 102.4 µs operating at pulse rates of up to 80 MHz. A pulse sequence is launched on all channels simultaneously through a single firing signal. Advanced features include delay resolution down to 0.78 ns and programmable 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 circuitry.

The LM96570 is packaged in a 32-pin WQFN.
