LTC2107 16-Bit, 210Msps High Performance ADC
Description
The LTC®2107 is a 16-bit, 210Msps high performance ADC. The bination 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 = 80d BFS, SFDR = 98d BFS. 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.
