Increment Output Phase Delay.
The INCDELAY and DECDELAY pins can adjust the
phase of the Si5364 clock outputs. Adjustment is
accomplished by driving a pulse (a transition from
low to high and then back to low) into one of the pins
while the other pin is held at a logic low level.
Each pulse on the INCDELAY pin adds a fixed delay
to the Si5364’s clock outputs. The fixed delay time is
equal to twice the period of the 622 MHz output clock
(t

the input clock. The frequency of the 622 MHz output
clock (fo_622) is scaled additionally according to the
setting of the FEC[1:0] pins.
When the phase of the Si5364 clock outputs is
adjusted using the INCDELAY and/or DECDELAY
pins, the output clock moves to its new phase setting
at a rate of change that is determined by the setting
of the BWSEL[1:0] pins.
Note: INCDELAY is ignored when the Si5364 is operating
Decrement Output Phase Delay.

phase of the Si5364 clock outputs. Adjustment is
accomplished by driving a pulse (a transition from
