Clock Generator

AK8126

Features

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

Output Frequency Range:

16MHz – 128MHz

Configurable Spread Spectrum Modulation:

- AKEMD’s Original Spread Spectrum

Profile

- Modulation Ratio:

Center Spread:

±0.25%, ±0.5%, ±1.0%, ±1.5%

Down Spread:
