Overview
The LA9511W is a transmitter IC developed for free-
space infrared transmission of stereo audio and video
signals. It integrates all the required functions for
transmission, including audio signal modulation, video
signal modulation, LED drive, and other functions on a
single chip. An AV coupler system can be implemented
easily using this IC and a receiver IC (such as the
LA9520V).
Functions
[Audio Block]
Audio input block ALC with wide AGC operating range
Integration of passive components used for preemphasis
and time constants onto the chip.
Deviation adjustment amplifier. Adjustable from an
externally applied voltage: supports an electronic
variable resistor function.
Filter: Removes unneeded high-frequency components.
Audio VCO. PLL circuit adopted for adjustment-free
operation.
[Video Block]
Video deviation amplifier. Adjustable from an externally
applied voltage: supports an electronic variable resistor
function.
Video preemphasis
Video VCO. f0 adjustment from an externally applied
voltage: supports an electronic variable resistor function.
Filter. Removes unneeded high-frequency components.
[Driver Block]
Mixer and driver amplifier. Features excellent high-
frequency characteristics and allows addition of external
data (remote control).

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.
