Notes:
7.
Test measurement levels for the PI6C3991 are TTL levels (1.5V to 1.5V). Test conditions assume signal transition times of 2ns or less
and output loading as shown in the AC Test Loads and Waveforms unless otherwise specified.
Guaranteed by statistical correlation. Tested initially and after any design or process changes that may affect these parameters.
SKEW is defined as 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 30pF and terminated with 50 Ohm to V
CC
/2.
10. t
SKEWPR
is defined as the skew between a pair of outputs (XQ0 and XQ1) when all eight outputs are selected for 0t
U
.
11. t
SKEW0
is defined as the skew between outputs when they are selected for 0t
U
. Other outputs are divided or inverted but not shifted.
12. C
L
= 0pF. For C
L
= 30pF, t
SKEW0
= 0.35ns.
13. There are three classes of outputs: Nominal (multiple of t
U
delay), Inverted (4Q0 and 4Q1 only with 4F0 = 4F1 = HIGH), and Divided
(3Qx and 4Qx only in Divide-by-2 or Divide-by-4 mode).
14. t
DEV
is the output-to-output skew between any two devices operating under the same conditions (V
CC
ambient temperature, air flow,
etc.)
15. t
ODCV
is the deviation of the output from a 50% duty cycle. Output pulse width variations are included in t
SKEW2
and t
SKEW4
specifications.
16. Specified with outputs loaded with 30pF for the PI6C3991 and PI6C3991-5 devices. Devices are terminated through 50 Ohm to V
CC
/
2. t
PWH
is measured at 2.0V. t
PWL
is measured at 0.8V.
17. t
ORISE
and t
OFALL
measured between 0.8V and 2.0V.
18. 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 limits. This parameter is measured from the application of a new signal or frequency at REF or FB until t
PD
is within
specified limits.
