TDA10021HT is a DVB-C channel receiver produced by Philips Semiconductors. It supports 4, 16, 32, 64, 128 and 256 Quadrature Amplitude Modulation (QAM) demodulators, high performance 256 QAM, especially for direct IF applications.
The TDA10021HT is a single-chip DVB-C channel receiver designed for 4, 16, 32, 64, 128, and 256 Quadrature Amplitude Modulation (QAM) signals. It interfaces directly to the IF signal using an on-chip 10-bit Analog-to-Digital Converter (ADC) and performs clock and carrier recovery functions. The device includes a programmable half Nyquist filter, adaptive equalizer, and a Forward Error Correction (FEC) decoder compliant with DVB-C standards.
