Si53303
2.4. Synchronous Output Enable
The Si53303 features a synchronous output enable (disable) feature. Output enable is sampled and synchronized
on the falling edge of the input clock. This feature prevents runt pulses from being generated when the outputs are
enabled or disabled.

Disabled
Note 1. Outputs are disabled after 1 to 2 negative edges of the input clock.
Figure 5. Synchronous Output Enable
When OE is low, Q is held low and Q is held high for differential output formats. For LVCMOS output format
options, both Q and Q are held low when OE is set low. The device outputs are enabled when the output enable pin
is unconnected.
