Note: A single TU/VT (number 21/28 in STS-1 number 3) is shown for illustration purposes. The A and B add bus outputs
A/BDCLK clock period
A/BDCLK duty cycle t
A/BD(7-0)/A/BDPAR data /parity setup time before A/BDCLK
A/BD(7-0)/A/BDPAR data /parity hold time after A/BDCLK
A/BDSPE setup time before A/BDCLK
A/BDSPE hold time after A/BDCLK
A/BDC1J1V1 setup time before A/BDCLK
A/BDC1J1V1 hold time after A/BDCLK
A/BACLK delay from A/BDCLK
A/BAC1J1V1 delay from A/BACLK
A/BASPE delay from A/BCLK
A/B(7-0) and A/BAPAR data /parity out valid delay from
A/BACLK
A/BADD delay from A/BACLK
Note: All output times are measured with the 50 pf load capacitance.
