AK4708
AV SCART Switch with Dual RGB Outputs
| The AK4708 is an I2C controlled audio and video switch matrix designed for digital TV and set-top-box applications. The AK4708 offers the ideal features for digital set-top-box systems. The AK4708 includes the audio switches, video switches, video filters. The AK4708 provides high performance audio and video routings to meet dual SCART connections. The AK4708 is supplied in a small 48-pin LQFP package to contribute space saving in PCB. |
