IF Signal Processing Circuit
(A
2C PLL VIF + SIF) for TVs and VCRs
Overview
The LA7583 is a VIF + SIF IC that requires no adjustments. In
order to eliminate the need for adjustments in the VIF block, a
multi-network PLL has been developed and adopted for video
detection. In the SIF block, adjustments were eliminated by
using gyrator technology in the FM quadrature detector. In
addition to eliminating the need for adjustments, a buzz
canceller that suppresses Nyquist buzz has been built into the
LA7583 in order to provide excellent sound quality.
Features
.
Elimination of VCO, AFT, and SIF coils eliminates the need
for adjustments.
.
A variety of built-in filters.
.
Built-in buzz canceller results in excellent audio
characteristics.
