DESCRIPTION
3.3V input for selecting PLL Band Width
0 = low, 1= high
"True" reference clock input.
"Complementary" reference clock input.
Output enable for SRC/PCI Express output pair '0'
0 = enabled, 1 = tri-stated
Power supply, nominal 3.3V
Ground pin.
True clock of differential PCI_Express pair.
Complement clock of differential PCI_Express pair.
Power supply, nominal 3.3V
Data pin of SMBUS circuitry, 5V tolerant
Clock pin of SMBUS circuitry, 5V tolerant
Power supply, nominal 3.3V
Complement clock of differential PCI_Express pair.
True clock of differential PCI_Express pair.
Ground pin.
Power supply, nominal 3.3V
Output enable for SRC/PCI Express output pair '1'
0 = enabled, 1 = tri-stated
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.
Ground pin for the PLL core.
3.3V power for the PLL core.
Note:
Pins preceeded by '**' have internal 120K ohm pull down resistors
