The AK4710/11’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.
