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.
