Features

Description

• Up to 52 MSPS Front-End Processing Rates (CLKIN)

and 35 MSPS Back-End Processing Rates (PROCCLK) digitized IF data into ﬁltered baseband data which can be

Clocks May Be Asynchronous

The HSP50214 Programmable Downconverter converts

processed by a standard DSP microprocessor. The

Programmable Downconverter (PDC) performs down

conversion, decimation, narrowband low pass ﬁltering, gain

scaling, re-sampling, and Cartesian to Polar coordinate

conversion.

• Processing Capable of >100dB SFDR8-

• Up to 255-Tap Programmable FIR

• Overall Decimation Factor Ranging from 4 to 16384

• Output Samples Rates to 8.2 MSP8-S with Output

Bandwidths to 625kHz Lowpass

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 program-

mable 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.

• 32-Bit Programmable NCO for Channel Selection and

Carrier Tracking

• Digital Re-Sampling Filter for Symbol Tracking Loops

and Incommensurate Sample-to-Output Clock Ratios

• Digital AGC with Programmable Limits and Sle8- 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 Discrimi-

nator for AFC Loops and Demodulation of AM, FM,

FSK, and DPSK

Ordering Information

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