LA7567GVA
Monolithic Linear IC
TV and VCR VIF/SIF IF Signal-Processing
Circuit with NTSC SPLIT Support
Overview
The LA7567GVA is an NTSC SPLIT support VIF/SIF IF IC that adopts a semi-adjustment-free system. The VIF block
adopts a technique that makes AFT adjustment unnecessary by adjusting the VCO, thus simplifying the adjustment
steps in the manufacturing process. PLL detection is adopted in the FM detector. A 5V power-supply voltage is used to
match that used in most multimedia systems. In addition, this IC also includes a buzz canceller to suppress Nyquist buzz
and provide high audio quality.
Functions
VIF block: VIF amplifier, PLL detector, BNC, RF AGC, EQ amplifier, AFT, IF AGC, buzz canceller.
First SIF block: first SIF, first SIF detector, AGC.
SIF block: multi-format SIF converter, limiter amplifier, PLL FM detector.
Features
No AFT or SIF coils are required, making these circuits adjustment free.
Built-in buzz canceller for excellent audio performance.
VCC = 5V, low power dissipation (250mW)
