资 源 简 介
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 porthas input level threshold detecTIon circuitry and an AGC controllerfor accommodating large dynamic ranges or situationswhere gain ranging converters are used. Dual 16-bit parallel outputports accommodate high data rate WBCDMA applications. On-chipinterpolating half-band can also be used to further increase theoutput rate. In addition, each parallel output port has a digitalAGC for output data scaling. Link port outputs are provided toenable glueless interfaces to ADI’s TigerSHARC® DSP core.
