LA75525VA
Overview
Monolithic Linear IC
For TV Sets and VCRs
VIF/SIF Signal-Processing IC
The LA75525VA is a completely adjustment-free NTSC VIF/SIF signal-processing IC for TV sets and VCRs. It supports IF frequencies of 45.75 and 58.75MHz. 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.
Features
* Automatic adjustment VCO (no external VCO coil is required). * Built-in audio carrier trap; an external circuit may be used if desired. * Digital AFT adopted. * FM radio receiver function.
