14-Bit, 92.16 MSPS, 4 & 6-Channel Wideband IF to Base Band Receiver

The AD6654 is a mixed-signal IF to base band receiver consisting of a 14-bit, 92.16 MSPS analog-to-digital converter (ADC) and a four/six channel, multi-mode digital down converter (DDC) capable of processing up to six WCDMA (Wideband Code Division Multiple Access) channels. It has been optimized for the demanding filtering requirements of wideband standards such as CDMA2000, UMTS, and TD-SCDMA. The AD6654 is used as part of a radio system that digitally demodulates and filters IF sampled signals.
