Measured with a 2.0V input signal, 50% duty cycle, all PECL loading with 50
to V
CC
–
2V. Output swing is
≥
400mV.
Specification for packaged product only.
f
MAX
is defined as the maximum input frequency while enduring a valid output. f
MAX
is limited by the input stage.
V
= 2.0V, V
= 0.8V, 50% duty cycle. Delay measured at 100MHz from the crossing of the input signal with V
CC
/2 as the crossing of the
differential output signal. See Figure 1.
Skew is measured between outputs under identical transitions.
Cycle-to-cycle jitter definition: The variation period between adjacent cycles over a random sample of adjacent cycle pairs.
T
JITTER_CC
= T
n
–
T
n+1
, where T is the time between rising edges of the output signal.
Total jitter definition: with an ideal clock input frequency of
≤
f
MAX
(device), no more than one output edge in 10
12
output edges will deviate by
more than the specified peak-to-peak jitter value.
If t
r
/t
f
is less than 350ps, the duty cycle distortion will increase beyond the duty cycle limits.
Set-up and hold times apply to synchronous applications that intend to enable/disable before the next clock cycle. For asynchronous applica-
tions set-up and hold times do not apply.
