Pin assignments
4. This pin is a reset configuration pin. It has a weak (~20 kΩ) internal pull-up P-FET that
is enabled only when the device is in its reset state. This pull-up is designed to be
overpowered by an external 4.7 kΩ resistor. If the signal is intended to be high after reset,
and if there is any device on the net that might pull down the value of the net at reset, a
pull-up or active driver is needed.
5. Pin must NOT be pulled down during power-on reset. This pin may be pulled up,
driven high, or if there are any connected devices, left in tristate. If this pin is connected
to a device that pulls down during reset, an external pull-up is required to drive this pin to
a safe state during reset.
6. Recommend that a weak pull-up resistor (4.7 kΩ) be placed on this pin to the
respective power supply.
7. This pin is an open-drain signal.
8. Recommend that a weak pull-up resistor (1 kΩ) be placed on this pin to the respective
power supply.
9. This pin has a weak (~20 kΩ) internal pull-up P-FET that is always enabled.
10. This is a test signal for factory use only and must be pulled up (100 Ω to 1 kΩ) to the
respective power supply for normal operation.
11. This pin requires a 200 Ω pull-up to respective power supply.
12. Do not connect. This pin should be left floating.
13. These pins must be pulled up to 1.2 V through a 180 Ω ± 1% resistor for MDC and a
330 Ω ± 1% resistor for MDIO.
14. This pin requires an external 1 kΩ pull-down resistor to prevent PHY from seeing a
valid Transmit Enable before it is actively driven.
15. Must be pulled to ground (GND).
16. This pin requires a 698 Ω pull-up to respective power supply.
17. This pin should be tied to ground if the diode is not utilized for temperature
monitoring.
18. If used as an SDHC signal, pull up 10 kΩ to 100 kΩ to the respective I/O supply.
19. New board designs should leave a placeholder for a parallel series resistor and
capacitor filter to be used in very close proximity to the USB_IBAIS_REXT pin of NXP
QorIQ chips. When needed, this allows for flexibility in populating them, which helps
