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 appl
