LA75676V-S

VIF/SIF IF Signal-Processing Circuit

for TV and VCR Products

Overview

The LA75676V-S is an NTSC intercarrier VIF/SIF IC that

adopts a semi-adjustment-free structure. In particular, it

uses VCO adjustment to make AFT adjustment

unnecessary and thus simplifies the overall adjustment

process. A PLL-based technique is adopted for FM

detection. The 5 V supply voltage provides compatibility

with other multimedia systems. In addition it achieves

high audio quality by incorporating a built-in buzz

canceller that suppresses Nyquist buzz.

Functions

[VIF]

• VIF amplifier • PLL detector • RF AGC• EQ amplifier

• AFT

• IF AGC • Buzz canceller

[SIF]

• Limiter amplifier • PLL FM detector

Features

• No AFT or SIF coils are used, thus eliminating

adjustments.

• Excellent audio performance due to the built-in buzz

canceller.

• VCC = 5 V and a low power dissipation of 250 mW.
