NOTES:
1. See ’Device Reset’ on page 108, Figure 4-33.
2. Alignment Jitter = measured from 100kHz to 148.5MHz
3. Alignment Jitter = measured from 1kHz to 27MHz
4. 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.
5. Single Ended into 75Ω external load.
6. ORL depends on board design. The GS1582 achieves this specification on Gennum’s evaluation boards.
