Description
The HSP50214A Programmable Downconverter converts dig-
itized IF data into filtered baseband data which can be pro-
cessed
by
a
standard
Programmable Downconverter (PDC) performs down conver-
sion, decimation, narrowband low pass filtering, gain scaling,
resampling, and Cartesian to Polar coordinate conversion.
DSP
microprocessor.
The
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 fil-
ters. The halfband filters are followed by a 255-tap pro-
grammable
FIR
filter.
The
programmable FIR filter is scaled by a digital AGC before
being re-sampled in a polyphase FIR filter. The output sec-
tion can provide seven types of data: Cartesian (I, Q), polar
(R, q), filtered frequency (dq/dt), Timing Error (TE), and
AGC level in either parallel or serial format.
