LA7137M

www.DataSheet4U.com Ordering number : EN6206 LA7137M Overview Monolithic Linear IC DVD Analog Video Output I/F IC The LA7137M is a video output interface IC for DVD players and is optimal as the driver IC for DVD players that provide composite signal/S signal, component signal, and RGB signal video outputs. Since this IC integrates a Y/C mixer on the same chip, the D/A converter composite output can be omitted. The LA7137M also integrates S1 and S2 DC voltage and D/A converter reference voltage generation on chip, allowing most components other than the drivers to be omitted. Functions Clamps Amplifier 75Ω driver Y/C mixer S1 and S2 DC output D/A converter reference voltage output Features Video signal-to-noise ratio : -80dB Frequency characteristics : flat to 10MHz Y/C time difference : less than 2ns Signal dynamic range : 170IRE. Can support all major signal types : composite/S signals, component signals, and baseband (RGB) signals. Furthermore, the IC input type can be switched by the system microcontroller (since the input capacitors are shared). Two 75Ω driver systems that can be independently muted by the system microcontroller. The clamp pulses required for component signal input are generated internally in the IC. Either of two amplifier gain levels, 8.5 and 6dB, can be selected. A built-in regulator circuit provides a stable DC voltage output that is independent of VCC fluctuations.
