HSP50214BVCZ - Renesas Electronics

Description: The HSP50214B Programmable Downconverter converts digitized IF data into filtered baseband data which can be processed by a standard DSP microprocessor. The Programmable Downconverter (PDC) performs down conversion, decimation, narrowband low pass filtering, gain scaling, resampling, and Cartesian to Polar coordinate conversion. The 14-bit sampled IF input is down converted to baseband by digital mixers and a quadrature NCO, as shown in the Block Diagram. A decimating (4 to 32) fifth order Cascaded Integrat
