AK8126

Spread Spectrum Clock Generator

Description

The is a spread spectrum clock generator designed for Home AV applications where EMI elimination is seriously required. The device uses the AKEMD’s original spread spectrum profile

.

* to provide excellent EMI reduction effect without degradation of system performance. The AK8126 accepts a wide clock frequency range from a crystal or reference clock input, and provides a variable spread spectrum modulation selectable by pin-setting, allowing the device to use in most AV products easily. The device is available in a very small 10-pin TMSOP package, and its pin configuration offers simple PCB layout.
