Question: What is clock jitter for HX2LP™ and HX2VL™?
Clock jitter for HX2LP and HX2VL is 0.05 percent.
Jitter is the undesired deviation from true periodicity of an assumed periodic signal in electronics and telecommunications, often in relation to a reference clock source.
According to the USB Implementers Forum (USB-IF) 2.0 spec, the high-speed data rate is nominally 480.00 Mbps, with a required bit rate accuracy of 500 ppm. For HX2LP and HX2VL, the required data rate accuracy when transmitting at any speed is 0.05 percent (500 ppm). The chip is designed following the USB-IF 2.0 spec.
If you drop out of this tolerance for a cycle, then the data will drop out of the required rate.
