DESCRIPTION
Programmable Clock Request pin for SRC/ATIG/SB_SRC outputs. If output is
selected for control, then that output is controlled as follows:
0 = Enabled, 1 = Tri-state
Complementary clock of low-power differential push-pull PCI-Express pair with
integrated 33 ohm series resistor. (no 50ohm shunt resistor to GND needed)
True clock of low-power differential push-pull PCI-Express pair with integrated
33 ohm series resistor. (no 50ohm shunt resistor to GND needed)
Ground pin for the ATIG outputs
Power supply for ATIG core, nominal 3.3V
Complementary clock of low-power differential push-pull PCI-Express pair with
integrated 33 ohm series resistor. (no 50ohm shunt resistor to GND needed)
True clock of low-power differential push-pull PCI-Express pair with integrated
33 ohm series resistor. (no 50ohm shunt resistor to GND needed)
Supply for SRC, 3.3V nominal
Ground pin for the SRC outputs
Complement clock of low power differential SRC clock pair with integrated 33
ohm series resistor. (no 50ohm shunt resistor to GND needed)
True clock of low power differential SRC clock pair with integrated 33 ohm series
resistor. (no 50ohm shunt resistor to GND needed)
No Connect
Ground for the Analog Core
3.3V Power for the Analog Core
Complementary signal of low-power differential push-pull AMD K8 "Greyhound"
clock with integrated 33 ohm series resistor. (no 50ohm shunt resistor to GND
needed)
