Maximum/minimum LVDS data transfer rate (f
Maximum/minimum LVDS data transfer rate (f
The timing difference between the fastest and slowest output edges, including t
variation and clock skew. The clock is included in the TCCS measurement.
The period of time during which the data must be valid in order to capture it
correctly. The setup and hold times determine the ideal strobe position within the
sampling window.
Peak-to-peak input jitter on high-speed PLLs.
Peak-to-peak output jitter on high-speed PLLs.
Duty cycle on high-speed transmitter output clock.
Lock time for high-speed transmitter and receiver PLLs.
