Ground pin.
Power supply for PCI Express clocks, nominal 3.3V
Complementary clock of differential pair CPU output. / Complementary clock of
differential PCIEX pair. These are 0.8V push pull outputs. No external 50ohm
resistor to GND or 33ohm series resistor needed.
True clock of differential pair CPU output. / True clock of differential PCIEX
pair. These are 0.8V push pull outputs. No external 50ohm resistor to GND or
33ohm series resistor needed.
Complementary clock of differential pair 0.8V push-pull CPU outputs with
integrated 33ohm series resistor.
True clock of differential pair 0.8V push-pull CPU outputs with integrated
33ohm series resistor.
Supply for CPU clocks, 3.3V nominal
Complementary clock of differential pair 0.8V push-pull CPU outputs with
integrated 33ohm series resistor.
True clock of differential pair 0.8V push-pull CPU outputs with integrated
33ohm series resistor.
Ground pin.
Clock pin of SMBus circuitry, 5V tolerant.
Data pin for SMBus circuitry, 5V tolerant.
Stops CPU0 clock when enabled.
Stops all PCICLKs at logic 0 level, when low. Free running PCICLKs are not
effected by this input.
Crystal output, Nominally 25.00MHz.
Crystal input, Nominally 25.00MHz.
Ground pin.
25MHz clock output, 3.3V
Supply for suspend mode, powers 25MHz PLL, 25M output and XTAL
oscillator. 3.3V Nominal
This active high 3.3V LVTTL input is a level sensitive strobe used to determine
when latch inputs are valid and are ready to be sampled / Asynchronous active
low input pin that stops all outputs except free running 25Mhz
