HSP50214BVIZ规格书详情
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.
