The AD6634 is a multimode 4-channel digital receive signal processor
(RSP) capable of processing up to two WCDMA channels.
Each channel consists of four cascaded signal processing elements:
a frequency translator, two fixed coefficient decimating filters,
and a programmable coefficient decimating filter. Each input port
has input level threshold detection circuitry and an AGC controller
for accommodating large dynamic ranges or situations
where gain ranging converters are used. Dual 16-bit parallel output
ports accommodate high data rate WBCDMA applications. On-chip
interpolating half-band can also be used to further increase the
output rate. In addition, each parallel output port has a digital
AGC for output data scaling. Link port outputs are provided to
enable glueless interfaces to ADI’s TigerSHARC® DSP core.
