TDA10021HT - DVB-C channel receiver

General Description

The TDA10021HT is a single-chip DVB-C channel receiver for 4, 16, 32, 64, 128 and 256 QAM modulated signals.

The device interfaces directly to the IF signal, which is sampled by a 10-bit ADC.

The TDA10021HT performs the clock and the carrier recovery functions.

Key Features

  • 4, 16, 32, 64, 128 and 256 Quadrature Amplitude Modulation (QAM) demodulator (DVB-C compatible: ETS 300-429/ITU-T J83 annex A/C).
  • High performance for 256 QAM, especially for direct IF.
