 | | Taking into account the impact of a transmitter and receiver clock jitter, channel skew and cross talk, the BER of an interface, power supply noise, device process, temperature, as well as EMI, then a practical data speed limitation can be derived from the minimum bit time and a specified eye diagram margin. |
 | | In the case of a multi-channel, the channel and package skew are an important contribution to the timing margin. |
 | | The channel and package skew can be as long as 140ps in some cases. |
