XRK4993

REV. 1.0.0

3.3V PROGRAMMABLE SKEW CLOCK BUFFER

NOTES:

These inputs are normally wired to VCC, GND or left unconnected (actual threshold voltages vary as a percentage

of VCC). Internal termination resistors hold unconnected inputs at VCC/2. If these inputs are switched, the function

and timing of the outputs may glitch and the PLL may require an addtional tLOCK time before all data sheet limits

are achieved.

XRK4993 should be tested one output at a time, output shorted for less than one second, less than 10% duty

cycle. Room temperature only.

Applies to CLKIN and FB_IN inputs only.
