LM96570SQE/NOPB

Specialized Overview

The LM96570 is an eight-channel monolithic beamformer for pulse generators in multi-channel medical ultrasound applications. It operates with a core supply voltage of 1.8 V and I/O voltage of 2.5 to 3.3 V. The device supports output pulse rates up to 80 MHz, driven by a reference frequency of 40 MHz. Key timing specifications include a delay resolution of 0.78 ns and a maximum delay range of 102.4 μs. Pulse patterns can extend up to 64 pulses per channel. The serial interface speed reaches 80 Mbps. Total power consumption is typically 0.063 Watts, and the operating temperature range is 0 to +70 °C.

Specialized Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet documentation. Confirm the package type matches the specified 32-lead LLP configuration. Ensure the ordering suffix corresponds to the required tape and reel quantity. Cross-reference the part number with the authorized distributor list to guarantee supply chain integrity and compliance with RoHS standards.

Specialized Selection Notes

Select this component for low-power, portable medical ultrasound systems requiring precise transmit beamforming. Ensure the design accommodates the 1.8 V core supply and 2.5 to 3.3 V I/O logic levels. Verify that the external reference clock meets the 40 MHz requirement for the internal PLL. Consider the companion LM965XX series chipset for a complete transmit/receive solution.

Specialized Part Context

The LM96570 belongs to the National Semiconductor (now Texas Instruments) LM965XX series, designed specifically for medical ultrasound applications. It serves as the configurable transmit beamformer within an 8-channel transmit/receive chipset architecture. This integration supports scalable system designs ranging from 128 to 256 channels when combined with other components in the family.
