DESCRIPTION:
The IDT5993A is a high fanout PLL based clock driver intended for
high performance computing and data-communications applications. A
key feature of the programmable skew is the ability of outputs to lead or
lag the REF input signal. The IDT5993A has six programmable skew
outputs and two zero skew outputs. Skew is controlled by 3-level input
signals that may be hard-wired to appropriate HIGH-MID-LOW levels.

NOTES:
1. All timing and jitter tolerances apply for FNOM > 25MHz.
2. Skew is the time between the earliest and the latest output transition among all outputs for which the same tU delay has been selected when all are loaded with the specified
load.
3. tSKEWPR is the skew between a pair of outputs (xQ0 and xQ1) when all eight outputs are selected for 0tU.
4. tSKEW0 is the skew between outputs when they are selected for 0tU.
5. For IDT5993A-2 tSKEW0 is measured with CL = 0pF; for CL = 30pF, tSKEW0 = 0.35ns Max.
6. There are two classes of outputs: Nominal (multiple of tU delay), and Divided (3Qx only in Divide-by-2 or Divide-by-4 mode).
7. tDEV is the output-to-output skew between any two devices operating under the same conditions (VCC, ambient temperature, air flow, etc.)
8. tLOCK is the time that is required before synchronization is achieved. This specification is valid only after VCC is stable and within normal operating limits. This parameter is
measured from the application of a new signal or frequency at REF or FB until tPD is within specified limits.
9. tPD is measured with REF input rise and fall times (from 0.8V to 2V) of 1ns.
10. Measured at 2V.
11. Measured at 0.8V.
