Tokyo Japan, August 4 2011, Asahi Kasei Microdevices Corporation (AKM) today launched the AK4710 and the AK4711, low power single AV line drivers for single SCART applications. Individual video output switches can be controlled via a serial I2C bus. The AK4710 has an SD video filter and line driver, while the AK4711 has both SD and HD video filters and line drivers. Both devices contain integrated audio drivers with ground referenced outputs, eliminating the need for large AC-coupling capacitors, reducing cost and saving board space. The new devices operate off of a single +3.3V power supply, reducing system power requirements.
The AK4710/11’s audio block accepts either single-ended or differential input from an external audio DAC. It is very flexible, with integrated volume controls that range from -6dB to +24dB for gain control. The video block includes a clamp circuit, video filters, video switches and a 75-ohm video line driver, realizing simple and low cost system construction
The AK4710/11 supports fast and slow video blanking, compatible with the European SCART standard, making the AK4710/11 ideal for a full spectrum of European digital AV products. The AK4710 is housed in a 32-pin QFN package, and the AK4711 is housed in a 36-pin QFN package. Evaluation boards and samples are available now.
