Analog Devices AD6635 4-Channel 80 MSPS WCDMA Receive Signal Processor Datasheet
The AD6635 is a multimode, 8-channel, digital Receive Signal Processor (RSP) capable of processing up to four WCDMA channels. Each channel consists of four cascaded signal-processing elements: a frequency translator, two CIC decimating filters, and a programmable coefficient-decimating filter. The device features quad 16-bit parallel output ports and on-chip interpolating half-band filters to accommodate high data rate WCDMA applications.
The architecture includes four independent automatic gain control (AGC) loops for direct interface to a RAKE receiver. It is part of Analog Devices' SoftCell Multicarrier transceiver chipset designed for compatibility with Analog Devices' family of high sample rate IF sampling ADCs. The RAM-based architecture allows easy reconfiguration for multimode applications, supporting GSM, IS136, EDGE, PHS, IS95, UMTS, and cdma2000.
