Atmel® announces a 10-bit A/D converter with a clock frequency of 2.2 Gs/s, providing high performance over 1st and 2nd Nyquist zones. The AT84AS008GL is fully pin-compatible with the company’s TS83102G0BGL 10-bit 2 Gs/s ADC, allowing for seamless upgrades and providing a full 8 Effective Number of Bits at 1.7 Gs/s in 1st Nyquist for high speed digitization applications such as broadband test & measurement equipment, high speed data acquisition, telecommunications and defense. The new device provides impressive dynamic performance of 55 dB SFDR and 51 dB SNR at 2.2 Gs/s in first Nyquist conditions. Furthermore, the 3.3 GHz input bandwidth extends ADC operation well into the 2nd Nyquist zone with essentially flat performance: SNR remains at 48 dB and SFDR at 55 dB. Interfacing the AT84AS008GL with FPGAs, DSPs or ASICs is possible through a new Atmel companion DMUX chip, AT84CS001TP.
