LA75520K
Monolithic Linear IC
IF Signal Processing (VIF+SIF) IC
that Supports the PAL Video
Standard for TV Sets and VCRs
Overview
The LA75520K is a fully adjustment-free VIF + SIF signal processing IC for TV sets and VTRs that supports the PAL
video standard. It supports 38.0MHz, 38.9MHz, and 39.5MHz as the IF frequencies, as well as PAL sound multi-system
(M/N, B/G, I and D/K), and contains an on-chip sound carrier trap. The IC employs a 4MHz frequency (which can be
switched to 4.43MHz) as the reference frequency of the adjustment free circuit, and controls the VCO, AFT, and sound
filter using an external input signal.
Features
Internal VCO adjustment free circuit eliminating the need for an external VCO coil.
Internal sound carrier trap enables easy configuration of PAL sound multi-system at low cost.
Considerably reduces the number of required peripheral parts.
Use of digital AFT eliminates a problem of AFT tolerance.
Package: DIP24S (300mil)
Functions
VIF amplifier
Adjustment-free VCO and PLL detector circuit
Digital AFT circuit
RF AGC
Buzz canceller
EQAMP
Internal sound carrier trap
First SIF detector circuit
PLL-FM detector circuit
