General part information

LTC2107 Series

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 = 45fsRMSallows 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.ApplicationsSoftware Defined RadiosMilitary Radio and RADARCellular Base StationsSpectral AnalysisImaging SystemsATE and Instrumentation
