NOTES:
1. Input setup and hold time is dependent on the rise and fall time on the parallel input. Parallel clock and data with rise time or fall time greater
than 500ps require larger setup and hold times.
2. Single Ended into 75Ω external load.
3. ORL depends on board design.
4. Alignment Jitter = measured from 100kHz to serial data rate/10.
5. Alignment Jitter = measured from 1kHz to 27MHz.
6. This is the maximum jitter for a BER of 10-12. The equivalent jitter value as per RP184 is 40ps max.
