AN5367FB

NTSC video, chroma, and deflection signal processing circuit

■ Overview

The AN5367FB is an IC to demodulate the NTSC composite signal. It is possible to control the all functions by the I

C bus. The use of flat package allows a space

saving in sets design.

■ Features

• Luminance signal processing

• Incorporating 3.58 MHz trap

• Black side gradation control is possible by black expansion circuit

• Adopting delay line aperture control

• Color signal processing

• Incorporating band-pass filter

• Incorporating ACC filter

• Deflection signal processing

• Stable sync. signal generation by the use of double AFC circuit and countdown circuit

• Vertical directional screen position is adjustable

• Others

• Incorporating 3-input composite signal changeover SW

• DAC output for adjusting sound volume and screen height
