AK8126 Datasheet | Asahi Kasei Microdevices

Features Output Frequency Range: 16MHz - 128MHz Configurable Spread Spectrum Modulation: - 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% - Modulation Frequency: 38.46KHz - 76.92KHz Input Frequency Range: - Crystal: 16MHz - 32MHz - Reference Clock Input : 16MHz - 128MHz - - : Patent pending Low Jitter Performance: 100 ps (Max.)
