ISL5216EVAL1 [INTERSIL]

The ISL5216 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 and four pairs of serial data outputs are provided. The ISL5216 supports both fixed and floating point parallel data input modes. The serial data output word width for each data type can be programmed to one of ten output bit widths from 4-bit fixed point through 32-bit IEEE 754 floating point. The ISL5216 is programmed through a 16-bit microprocessor interface. The output data can also be read via the microprocessor interface for all channels that are synchronized. The ISL5216 is specified to operate to a maximum clock rate of 95MSPS over the industrial temperature range (-40°C to 85°C).
