Texas Instruments  LM97937RMER

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. The integrated input buffer reduces charge kick-back noise and eases the system level design of the driving amplifier, anti-aliasing filter and impedance matching. An input sampling clock divider provides integer divide ratios with configurable phase selection to simplify system clocking. The device comes in a 56-pin, 8-mm × 8-mm QFN package.
