Features

Description

• Up to 65 MSPS Front-End Processing Rates (CLKIN) and

55 MSPS (41 MSPS Using the Discriminator) Back-End

Processing Rates (PROCCLK)

The HSP50214A Programmable Downconverter converts dig-

itized IF data into filtered baseband data which can be pro-

cessed by

standard DSP microprocessor. The

Clocks May Be Asynchronous

Programmable Downconverter (PDC) performs down conver-

sion, decimation, narrowband low pass filtering, gain scaling,

resampling, and Cartesian to Polar coordinate conversion.

• Processing Capable of >100dB SFDR

• Up to 255-Tap Programmable FIR

Pro-

• Overall Decimation Factor Ranging from 4 to 16384

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 output data from 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.

• Output Samples Rates to 12.94 MSPS with Output Band-

widths to 982kHz Lowpass

• 32-Bit Programmable NCO for Channel Selection and Car-

rier Tracking

• Digital Resampling Filter for Symbol Tracking Loops and

Incommensurate Sample-to-Output Clock Ratios

• Digital AGC with Programmable Limits and Slew Rate to

Optimize Output Signal Resolution; Fixed or Auto Gain

Adjust

• Serial, Parallel, and FIFO 16-Bit Output Modes

• Cartesian to Polar Converter and Frequency Discriminator

for AFC Loops and Demodulation of AM, FM, FSK, and

DPSK

Ordering Information

• Input Level Detector for External I.F. AGC Support
