AC ELECTRICAL CHARACTERISTICS
LVPECL: V
CC = 2.375V to 3.63V, VEE = 0V; PECL: VCC = 4.50V to 5.50V, VEE = 0V
LVECL: V
CC = 0V, VEE = –2.375V to –3.63V; ECL: VCC = 0V, VEE = –4.50V to –5.5V
Notes:
1. f
MAX is defined as the maximum toggle frequency. Measured with 750mV input signal, 50% duty cycle, output swing ≥ 400mV (diff), all loading with 50
to V
CC–2V.
2. Skew is measured between outputs under identical transitions.
3. Set-up and hold times apply to synchronous applications that intend to enable/disable before the next cycle. For asynchronous applications, set-up and
hold time does not apply.
4. Cycle-to-cycle jitter definition: The variation in period between adjacent cycles over a random sample of adjacent cycle pairs. TJITTER_CC =Tn–Tn+1 where
T is the time between rising edges of the output signal.
5. Total jitter definition: with an ideal clock input applied to one channel of the MUX, no more than one output edge in 1012 output edges will deviate by more
than the specified peak-to-peak jitter value.
