CXA3218N - FM Demodulator for BS/CS

Description

The CXA3218N is the video signal demodulation IC for satellite broadcasting.

This IC has most of the functions required for demodulation, and provides stable video detection in combination with the CXA3108Q (L-band down converter with PLL).

Features

  • Built-in IF AGC.
  • Excellent DG/DP characteristics.
  • Keyed AFT input pin to support MUSE reception.
  • 1st AGC control output pin.
  • Single 5 V power supply operation.
