NOTES:
1. All timng and jitter tolerances apply for F
NOM
> 25MHz.
2. Skew is the time between the earliest and the latest output transition among all outputs for which the same t
U
delay has been selected when all are loaded with the specified
load.
3. t
SKEWPR
is the skew between a pair of outputs (xQ
0
and xQ
1
) when all eight outputs are selected for 0t
U
.
4. t
SKEW0
is the skew between outputs when they are selected for 0t
U
.
5. For IDT5993A-2 t
SKEW0
is measured with C
L
= 0pF; for C
L
= 30pF, t
SKEW0
= 0.35ns Max.
6. There are two classes of outputs: Nomnal (multiple of t
U
delay), and Divided (3Qx only in Divide-by-2 or Divide-by-4 mode).
7. t
DEV
is the output-to-output skew between any two devices operating under the same conditions (V
CC
, ambient temperature, air flow, etc.)
8. t
LOCK
is the time that is required before synchronization is achieved. This specification is valid only after V
CC
is stable and within normal operating limts. This parameter is
measured fromthe application of a new signal or frequency at REF or FB until t
PD
is within specified limts.
9. t
PD
is measured with REF input rise and fall times (from0.8V to 2V) of 1ns.
10. Measured at 2V.
11. Measured at 0.8V.
