50ohm shunt resistor to GND and no 33 ohm series resistor needed)
True clock of low-power differential push-pull ATIG pair with integrated series resistor. (no 50ohm
shunt resistor to GND and no 33 ohm series resistor needed)
Ground pin
Ground for the Analog Core
Complementary signal of low-power differential push-pull AMD K8 "Greyhound" clock with integrated
series resistor.(no 33 ohm series resistor needed)
True signal of low-power differential push-pull AMD K8 "Greyhound" clock with integrated series
resistor. (no 33 ohm series resistor needed)
Ground pin for the CPU outputs
Complementary signal of low-power differential push-pull AMD K8 "Greyhound" clock with integrated
series resistor. (no 33 ohm series resistor needed)
True signal of low-power differential push-pull AMD K8 "Greyhound" clock with integrated series
resistor.(no 33 ohm series resistor needed)
Enter /Exit Power Down.
0 = Power Down, 1 = normal operation.
Open Drain I/O. As an input it restores the PLL's to power up default state. As an output, this signal
is driven low when the internal watchdog hardware timer expires. It is cleared when the internal
watchdog hardware timer is reset or disabled. The input is falling edge triggered.
0 = Restore Settings, 1 = normal operation.
Complementary signal of low-power differential push-pull hypertransport clock with integrated series
resistor. (no 50ohm shunt resistor to GND and no 33 ohm series resistor needed) / 3.3V single ended
66MHz hyper transport clock
True signal of low-power differential push-pull hypertransport clock with integrated series resistor. (no
50ohm shunt resistor to GND and no 33 ohm series resistor needed) / 3.3V single ended 66MHz
hyper transport clock
14.318 MHz reference clock, 3.3V
14.318 MHz 3.3V reference clock
14.318 MHz 3.3V reference clock./ 3.3V tolerant latched input to select Hyper Transport Clock
Frequency.
0 = 100MHz differential HTT clock, 1 = 66MHz 3.3V single ended HTT clock
