LA75525AVA
Monolithic Linear IC
For TV and VCR sets
VIF/SIF Signal-Processing IC
Overview
The LA75525AVA is a completely adjustment-free NTSC VIF/SIF signal-processing IC for TV sets and VCRs. It supports
IF frequencies of 45.75MHz. It integrates an automatic adjustment circuit for the VCO, an AFT circuit, and an audio carrier
trap circuit on the same chip and requires the input of either a 4MHz or 3.58MHz reference signal.
Functions
• VIF block: VIF amplifier, buzz canceller, IF-VCO, PLL detector, IF-AGC, RF-AGC, digital AFT, equalizer amplifier
• 1stSIF block: 1stSIF amplifier,1stSIF detector
• SIF block: Limiter amplifier, PLL FM detector
• Others: reference frequency changeover SW, AFT mute voltage SW
