DESCRIPTION
NAME
NO.
Phase select pin. For a clock master, a resistor from this pin to GND determines the CLKIO output. When
configured as a clock slave, a resistor from the pin to GND selects the phase relationship that the slave has

with the master. Allowing this pin to float causes the slave to drop off line to shed the phase when current
demands are light for improved overall efficiency. See the Application Information section for more details.
