LTC2107 16-Bit, 210Msps High Performance ADC Features Description n 98dBFS SFDR The LTC 2107 is a 16-bit, 210Msps high performance ADC. n 80dBFS SNR Noise Floor The combination of high sample rate, low noise and high n Aperture Jitter = 45fs linearity enable a new generation of digital radio designs. RMS n PGA Front-End 2.4V or 1.6V Input Range The direct sampling front-end is designed specifically for P-P P-P n Optional Internal Dither the most demanding receiver applications such as software n Optional Data Output Randomizer defined radio and multi-channel GSM base stations. The n Power Dissipation: 1280mW AC performance includes, SNR = 80dBFS, SFDR = 98dBFS. n Shutdown Mode Aperture jitter = 45fs allows direct sampling of IF RMS n Serial SPI Port for Configuration frequencies up to 500MHz with excellent performance. n Clock Duty Cycle Stabilizer Features such as internal dither, a PGA front-end and n 48-Lead (7mm 7mm) QFN Package digital output randomization help maximize performance. Modes of operation can be controlled through a 3-wire serial interface (SPI). a The double data rate (DDR) low voltage differential (LVDS) n Software Defined Radios digital outputs help reduce digital line count and enable n Military Radio and RADAR space saving designs. n Cellular Base Stations n L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Spectral Analysis Technology Corporation.
