PCI clock output.
Ground pin for the PCI outputs
Asynchronous active low input pin used to power down the device. The
internal clocks are disabled and the VCO and the crystal are stopped.
Ground pin.
3.3V power for the PLL core.
Ground pin for the PLL core.
This pin establishes the reference current for the differential current-mode
output pairs. This pin requires a fixed precision resistor tied to ground in
order to establish the appropriate current. 475 ohms is the standard value.
3.3V power for the PLL core.
True clock of differential SRC clock pair.
Complement clock of differential SRC clock pair.
True clock of differential SRC clock pair.
Complement clock of differential push-pull SRC clock pair.
True clock of differential SRC clock pair.
Complement clock of differential SRC clock pair.
Supply for SRC clocks, 3.3V nominal
Ground pin for the SRC outputs
