Vendor: WASIELA Category: Modulation Demodulation

DVB-C Demodulator

The demodulator is designed to be used together with a cable tuner and an analog to digital converter (ADC).

Overview

The demodulator is designed to be used together with a cable tuner and an analog to digital converter (ADC).
The system has an internal state machine to control the operation, which can be externally configured via the SPI interface. A typical system application is shown in Figure 1.

This DVB-C QAM demodulator is supplied as a portable and synthesizable Verilog-2001 IP. The system is designed to be used in conjunction with a standard cable tuner. The QAM signal is acquired blindly, and QAM signal constellations from QAM 16 through QAM 256 are supported. The operation of the demodulator is automated by a master finite state machine.
