ADI AD6654BBCZ

The AD6654 is a mixed-signal IF-to-baseband receiver consisting of a 14-bit, 92.16 MSPS analog-to-digital converter (ADC) and a 4-/6-channel, multimode digital down-converter (DDC) capable of processing up to six WCDMA (wideband code division multiple access) channels. The AD6654 has been optimized for the demanding filtering requirements of wideband standards such as CDMA2000, UMTS, and TD-SCDMA, but is flexible enough to support wider standards such as WiMAX. It is typically used as part of a radio system that digitally demodulates and filters IF sampled signals.
