Ordering number : ENN6468 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).
