DESCRIPTION
Ground pin.
Complement clock of differential PCI_Express pair.
True clock of differential PCI_Express pair.
Complement clock of differential PCI_Express pair.
True clock of differential PCI_Express pair.
Power supply for PCI Express clocks, nominal 3.3V
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.
Ground pin.
Complimentary clock of differential pair CPU outputs. These are current
mode outputs. External resistors are required for voltage bias.
True clock of differential pair CPU outputs. These are current mode
outputs. External resistors are required for voltage bias.
Supply for CPU clocks, 3.3V nominal
Complimentary clock of differential pair CPU outputs. These are current
mode outputs. External resistors are required for voltage bias.
True clock of differential pair CPU outputs. These are current mode
outputs. External resistors are required for voltage bias.
Data pin for SMBus circuitry, 5V tolerant.
Clock pin of SMBus circuitry, 5V tolerant.
Ref, XTAL power supply, nominal 3.3V
Crystal output, Nominally 14.318MHz
Crystal input, Nominally 14.318MHz.
Ground pin.
14.318 MHz reference clock.
14.318 MHz reference clock./ 3.3V tolerant input for CPU frequency
selection. Refer to input electrical characteristics for Vil_FS and Vih_FS
values.
Real time system reset signal for frequency gear ratio change or watchdog
timer timeout. This signal is active low.
PCI clock output.
