Ordering number : ENN6469A
Monolithic Linear IC
LA9520V
AV Coupler Receiver
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 Ω 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.
