Description
The AK8126 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.
AKEMD’s Original Spread Spectrum Profile Modulation Ratio:
Center Spread: ±0.25%, ±0.5%, ±1.0%, ±1.5% Down Spread: -0.5%, -1.0%, -2.0%, -3.0%
