■ Overview

The AN3479FBP is an IC designed for NTSC-dedicated
VHS VCR signal processing and incorporates circuits for
processing RF and normal audio signals as well as lumi­nance and chroma signals.

■ Features

•

Compatible with I

•

Totally free of adjustments

•

Low-frequency comb system

•

An improved chroma S/N ratio ensured by built-in CNR
and CPC(chroma phase compensator) circuits

•

Compatible with SQPB

■ Precautions for use

1. The latch-up level of pin 8 is low about 140 V(200 pF).
Please be careful when handling the pin.

2.

Pay attention well to the handling because upside-down mounting may result in over-current, and characteristics
deterioration
