DESCRIPTION
Crystal input, Nominally 14.318MHz.
Crystal output, Nominally 14.318MHz
Ref, XTAL power supply, nominal 3.3V
Frequency select latch input pin / 14.318 MHz reference clock.
Frequency select latch input pin / 14.318 MHz reference clock.
Frequency select latch input pin / 14.318 MHz reference clock.
Ground pin for the REF outputs.
Power pin for the 48MHz output.3.3V
48MHz clock output.
48MHz clock output.
48MHz clock output.
Ground pin for the 48MHz outputs
Clock pin of SMBus circuitry, 5V tolerant.
Data pin for SMBus circuitry, 3.3V tolerant.
Power supply for PCI clocks, nominal 3.3V
Frequency select latch input pin / 3.3V PCI clock output.
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
