AN5076 - Guidelines for Selecting Reference Clock Input of the HOTLink II™ Device in Datacom Applications
|类别||汽车电子 > 应用笔记|
The purpose of this application note is to analyze one of the contributors of jitter in the serial output, namely the phase noise present in the reference source. The bit-rate clock that clocks the shift register is a multiple of the reference clock. Hence, a portion of the jitter on the reference clock is transferred to the serial bit rate clock which in turn translates to jitter at the serial data output.
