M61140FP - TUNER SINGLE CHIP

General Description

The M61140FP is a semiconductor integrated circuit consisting of Tuner signal processing for NTSC color TV and VCRs.

The circuit includes Mixer circuit in Tuning system, Oscillator circuit, PLL frequency synthesizer and VIF/SIF, which permits a smaller tuner system.

Key Features

  • VIF/SIF Inter carrier type for NTSC Coil-less VCO Adjustment free AFT High-speed IF AGC.
  • PLL Low phase noise and High-speed lock-up Built-in band switch driver (4 port) I2C bus control Available for both XO and external reference.
  • Mixer/Oscillator Built-in U&V Oscillator and mixer Built-in IF Amplifier (Unbalanced Output).
