Note: A single TU/VT (number 21/28 in STS-1 number 3) is shown for illustration purposes. The A and B add bus out-
A/BACLK
A/BASPE
ACLK clock period
ACLK duty cycle, t
AC1J1V1 setup time before ACLK
AC1J1V1 hold time after ACLK
ASPE setup time before ACLK
ASPE hold time after ACLK
A(7-0)/APAR data /parity out valid delay from ACLK
A(7-0)/APAR data /parity to tristate delay from ACLK
ADD add indicator delayed from ACLK
A(7-0)/APAR data /parity out tristate to driven delay
from ACLK
Note: All output times are measured with the specified load capacitance.
