LA75520VA
Overview
Monolithic Linear IC
VIF / SIF Signal-Processing Circuit
The LA75520VA is a completely adjustment-free PAL VIF/SIF IC for TV sets and VCRs. It supports IF frequencies of 38,
38.9, and 39.5MHz. 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 4.43MHz reference signal.
Features
•
Automatic adjustment VCO (no external VCO coil is required).
•
Built-in audio carrier trap supports the B/G, I, D/K, and M/N audio systems.
•
Digital AFT adopted.

Any and all SANYO Semiconductor products described or contained herein do not have specifications
that can handle applications that require extremely high levels of reliability, such as life-support systems,
aircraft's control systems, or other applications whose failure can be reasonably expected to result in
serious physical and/or material damage. Consult with your SANYO Semiconductor representative
nearest you before using any SANYO Semiconductor products described or contained herein in such
applications.
SANYO Semiconductor assumes no responsibility for equipment failures that result from using products
at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition
ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor
products described or contained herein.

Specifications of any and all SANYO Semiconductor products described or contained herein stipulate the
performance, characteristics, and functions of the described products in the independent state, and are
not guarantees of the performance, characteristics, and functions of the described products as mounted
in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an
independent device, the customer should always evaluate and test devices mounted in the customer's
products or equipment.
SANYO Semiconductor Co., Ltd. strives to supply high-quality high-reliability products. However, any
and all semiconductor products fail with some probability. It is possible that these probabilistic failures
could give rise to accidents or events that could endanger human lives, that could give rise to smoke or
fire, or that could cause damage to other property. When designing equipment, adopt safety measures
so that these kinds of accidents or events cannot occur. Such measures include but are not limited to
protective circuits and error prevention circuits for safe design, redundant design, and structural design.
