LM97937
Overview
The LM97937 device is a dual-channel 370 MSPS analog-to-digital converter (ADC) with JESD204B interface operating up to 7.4 Gb/s. SNRBoost technology with bandpass spectral shaping improves the noise density at the intermediate frequency and Bit-Burst technology provides temporary and periodic resolution enhancement.
