Output Enable

Each output of SY75603A/03B/04A/04B has an active

low Output Enable (OExb) control pin. Output Enable

and Disable function is synchronous with the input

clock which results in glitchless transitions as shown in

Figure 4-5 and Figure 4-6. The OExb is sampled on the

falling edge of the differential input (or falling edge of

IN_p signal). It takes 3.5 clock cycles of the input clock

to enable an output and 4.5 clock cycles to disable the

output, after the change of OExb is sampled.
