This document introduces the Intersil HSP50210 Digital Costas Loop, which can be used to demodulate BPSK, QPSK, 8-PSK, OQPSK, FSK, AM and FM waveforms.
The HSP50210 Digital Costas Loop (DCL) is a mixed‑signal IC that performs baseband processing for demodulating BPSK, QPSK, 8‑PSK, OQPSK, FSK, AM and FM waveforms. It includes a complex multiplier, selectable matched filters, AGC, carrier and symbol tracking loops, and a soft‑decision slicer, and is intended to be used together with the HSP50110 Digital Quadrature Tuner.
The document provides a functional description, pinout diagram, pin descriptions, ordering information, and timing diagrams. Key specifications such as clock rate, package type, temperature range and RoHS compliance are listed, along with register maps and configuration details for the internal loops and filters.
