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 Integrator-Comb (CIC) filter can be applied to the data before it is processed by up to 5 decimate-by-2 halfband filters. The halfband filters are followed by a 255-tap programmable FIR filter. The output data from the programmable FIR filter is scaled by a digital AGC before being re-sampled in a polyphase FIR filter. The output section can provide seven types of data: Cartesian (I, Q), polar (R, θ), filtered frequency (dθ/dt), Timing Error (TE), and AGC level in either parallel or serial format.
