Power supply ground.
2.25 to 3.65V or 1.8V +/-5% positive power supply
External clock input pin. VSS to VDD CMOS level.
Crystal oscillator enable pin. If OE1=OE2=OE3=0 then OE_OSC=0.
OE_OSC=1 for all the other OE1/2/3 logic states.
Output enable pin for CLKOUT3. The input has 150kΩ-typ on-chip pull-
down resistor.
Output enable pin for CLKOUT1. The input has 150kΩ-typ on-chip pull-
down resistor.
Output enable pin for CLKOUT2. The input has 150kΩ-typ on-chip pull-
down resistor.
Clock output-1. Clock frequency is the same as CLKIN.
Clock output-2. Clock frequency is the same as CLKIN.
Clock output-3. Clock frequency is the same as CLKIN.
