6.6 Timing Requirements, Propagation Delay, and Output Skew

MINTYPMAXUNIT
tPD_HCSLPropagation delay CLKin-to-HCSL (1)(2)RT = 50 Ω to GND, CL ≤ 5 pF295590885ps
tPD_CMOSPropagation delay CLKin-to-LVCMOS(1)(2)CL ≤ 5 pFVCCO = 3.3 V90014752300ps
VCCO = 2.5 V100015502700
tSK(O)Output skew(11)(9)(4)Skew specified between any two CLKouts. Load conditions are the same as propagation delay specifications.3050ps
tSK(PP)Part-to-part output skew(1)(2)(3)80120ps
(1) AC timing parameters for HCSL or CMOS are dependent on output capacitive loading.
(2) Parameter is specified by design, not tested in production.
(3) Output skew is the propagation delay difference between any two outputs with identical output buffer type and equal loading while operating at the same supply voltage and temperature conditions.
(4) Specification is ensured by characterization and is not tested in production.
