Used for test purposes only.
Must be pulled high for normal operation.
Used for test purposes only.
Must be pulled high for normal operation.
Used as a reset input to the device after power up conditions have
been met. Power up conditions include the power supplies reaching
a safe stable condition and the PLL achieving a locked state and the
PWRON_RESET_N coming to an active state prior to the
RESET_IN_N coming to an active state.
Signal used at power up to reset all internal logic to a known state
after the PLL has achieved a locked state. The PWRON_RESET_N
input is a 1.3-V tolerant only.
Used for test purposes only.
Must be pulled high for normal operation.
Signal used to inform external reset logic that the internal PLL has
achieved a locked state.
Signal used to control PCI drive strength characteristics. Drive
strength is varied on PCI address, data and control signals.
Pin requires a 34-Ω +/- 1% tolerance resistor to ground. Refer to
