HSP50214B TM Data Sheet May 2000 File Number 4450.3 Programmable Downconverter [ /Title digitized IF data into filtered baseband data which can be (HSP5 processed by a standard DSP microprocessor. The 0214B) Programmable Downconverter (PDC) performs down conversion, decimation, narrowband low pass filtering, gain /Subscaling, resampling, and Cartesian to Polar coordinate ject conversion. (ProThe 14-bit sampled IF input is down converted to baseband gramby digital mixers and a quadrature NCO, as shown in the mable Block Diagram. A decimating (4 to 32) fifth order Cascaded Down- Integrator-Comb (CIC) filter can be applied to the data conbefore it is processed by up to 5 decimate-by-2 halfband verter) filters. The halfband filters are followed by a 255-tap /Autho programmable FIR filter.
