VES1820X - SINGLE CHIP DVB-C CHANNEL RECEIVER

General Description

The VES1820X is a single chip channel receiver for 16, 32, 64, 128 and 256-QAM modulated signals.

The device interfaces directly to the IF signal, which is sampled by a 9-bit AD converter.

The VES1820X performs the clock and the carrier recovery functions.

Key Features

  • 16/32/64/128/256 QAM demodulator (DVB-C compatible : ETS 300-429).
  • On chip 9-bit ADC.
  • On chip PLL for crystal frequency multiplication.
  • Digital down conversion.
  • Half Nyquist filters (roll off = 15 %).
  • Automatic gain control PWM output (AGC).
  • Symbol timing recovery, with programmable second order loop filter.
  • Variable symbol rate capability from SACLK/64 to SACLK/4 (SACLK max = 36 MHz).
  • Programmable anti-alia.
