The LTC2107 is a 16-bit, 210Msps high performance ADC. The combination of high sample rate, low noise and high linearity enable a new generation of digital radio designs. The direct sampling front-end is designed specifically for the most demanding receiver applications such as software defined radio and multi-channel GSM base stations. The AC performance includes, SNR = 80dBFS, SFDR = 98dBFS. Aperture jitter = 45fs_RMS allows direct sampling of IF frequencies up to 500MHz with excellent performance.

Features such as internal dither, a PGA front-end and digital output randomization help maximize performance. Modes of operation can be controlled through a 3-wire serial interface (SPI).

The double data rate (DDR) low voltage differential (LVDS) digital outputs help reduce digital line count and enable space saving designs.
