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).
