Monolithic Linear IC
LA9511W
AV Remote Coupler Transmitter
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).
