Complementary clock of differential SRC clock pair.
True clock of differential SRC clock pair.
Ground for ATI Gclocks, nominal 3.3V
Power supply ATI Gclocks, nominal 3.3V
Complement clock of differential SRC clock pair.
True clock of differential SRC clock pair.
Supply for SRC clocks, 3.3V nominal
Ground pin for the SRC outputs
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.
Complementary clock of differential 3.3V push-pull K8 pair.
True clock of differential 3.3V push-pull K8 pair.
Ground pin for the CPU outputs
Supply for CPU clocks, 3.3V nominal
Complementary clock of differential 3.3V push-pull K8 pair.
True clock of differential 3.3V push-pull K8 pair.
Ground pin for the HTT outputs
3.3V Hyper Transport output
Supply for HTT clocks, nominal 3.3V.
Ground pin for the PCI outputs
PCI clock output.
Power supply for PCI clocks, nominal 3.3V
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.
