HSP50110 Data Sheet January 1999 File Number 3651.
4 Digital Quadrature Tuner The Digital Quadrature Tuner (DQT) provides many of the functions required for digital demodulation.
These functions include carrier LO generation and mixing, baseband sampling, programmable bandwidth filtering, baseband AGC, and IF AGC error detection.
Serial control inputs are provided which can be used to interface with external symbol and carrier tracking loops.
These elements make the DQT ideal for demodulator applications with multiple operational modes or data rates.
The DQT may be used with HSP50210 Digital Costas Loop to function as a demodulator for BPSK, QPSK, 8-PSK OQPSK, FSK, FM, and AM signals.
The DQT...
