LA75525VA
Monolithic Linear IC
For TV Sets and VCRs
VIF/SIF Signal-Processing IC
Overview
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.

A: IF system SW
The IF frequency becomes 45.75MHz when pin 10 is open.
The IF frequency becomes 58.75MHz when pin 10 is set to VCC.
B: Split / Inter carrier SW
Inter-carrier is selected by setting the 1st SIF input (pin 13) to GND.
C: Reference frequency changeover SW
The reference frequency becomes 3.58MHz when pin 11 is set to “C-c.”
This frequency becomes 4.0MHz when this pin is set to “C-d.”
