AD6634 and AD6635 are receive signal processors with wideband inputs and multiple functions, suitable for communication systems such as WCDMA and GSM/EDGE.
The document details the features of the AD6634 Receive Signal Processor, which is designed to process multiple cellular communication channels. Key capabilities include handling 80 MSPS wideband inputs (14 linear bits plus 3 RSSI) and processing two WCDMA channels or four GSM/EDGE channels within a single package.
The device features programmable digital AGC loops with a 96 dB range, digital resampling for noninteger decimation rates, and programmable decimating FIR filters. It also includes interpolating half-band filters, flexible control for multicarrier and phased array systems, and user-configurable built-in self-test (BIST) capability.
