Product Summary

The ISL5216KI is a 4-channel digital receiver integrated circuit offering exceptional dynamic range and flexibility. Each of the four channels consists of a front-end NCO, digital mixer, and CIC-filter block and a back-end FIR, AGC and Cartesian to polar coordinate-conversion block. The parameters for the four channels are independently programmable. Four 17-bit parallel data input busses (A(15:-1), B(15:-1), C(15:-1) and D(15:-1)) and four pairs of serial data outputs (SDxA, SDxB, SDxC, and SDxD; x = 1 or 2) are provided. Each input can be connected to any or all of the internal signal processing channels, Channels 0, 1, 2 and 3. The output of each channel can be routed to any of the serial outputs. Outputs from more than one channel can be multiplexed through a common output if the channels are synchronized. It is ideal for: (1)narrow-band tdma through is-95 cdma digital software radio and basestation receivers; (2)wide-band applications: w-cdma and umts digital software radio and basestation receivers.
