Overview
The LA9520V is a receiver IC developed for free-space
infrared transmission of stereo audio and video signals. It
integrates all the required functions for reception,
including I/V conversion for the received signal, a
preamplifier, ALC, audio signal demodulation, and video
signal demodulation functions, on a single chip. An AV
coupler system can be implemented easily using this IC
and a transmitter IC (such as the LA9511W or
LA9512W).
Functions and Features
[Input Block]
I/V conversion featuring excellent wideband characteristics
Preamplifier ALC with wide ALC operating range
[Audio Block]
Audio demodulator: Built-in 4.3 and 4.8 MHz demodulation
circuits.
Muting function: Mutes the output stage when there is
no input signal. The muting function operating level can
be adjusted from an input pin.
Output amplifiers: The right and left levels can be
adjusted by applying voltages to input pins. Electronic
volume control support.
[Video Block]
Video demodulator
Video amplifier: Supports 75
drive. Adjustable output
level: supports an electronic volume control.
Muting function: Mutes the output stage when there is
no input signal. The muting function operating level can
be adjusted from an input pin.
Filter: Removes unneeded high-frequency components.

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 Electric 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.
