Series Termination Resistors:
50 Ohms as per TI spec. Place
resistors as close to driving
source as possible. Termination
recommended for ALL MII signals

- Auto Negotiation Enable (All speeds / duplex supported)
(AN_EN, AN0 and AN1 all Internal PullUP)
- Operating Mode (MII or RMII)
(SNI_Mode Internal PullDown, MII_Mode control via jumper)
- LED Configuraiton (Mode1)
(LED_CFG Internal PullUp)
- MDIX Enable (Auto MDIX Enabled)
(MDIX_EN Internal PullUP)
- Physical Address (set to 0b00001)
(PHYAD[0] Internal PullUp, PHYAD[1..4] Internal PullDown)
(MII_MODE)
Posn 1-2 for MII (default)
Posn 2-3 for RMII
Pulse J1011F21PNL
(Includes built in
transformer)
Layout Note - Place Caps

Layout Note:
Place 0.1uF cap close

TANT as close to pin
23 as possible
PFBOUT PFBIN2 PFBIN1
50MHz Osc for RMII and 25MHz XTAL for MII
(TANT)
Reset Control:
- Reset from MCU Reset Out (will reset with MCU)
- Reset from GPIO. Allows MCU to reset PHY as well as hold PHY in reset
while reset config data can be driven onto pins to change mode etc.
Boot Configuration (using PHY internal Pulls)
MDIO Pullup
Layout Note:
MII Mode resistor (MII / RMII mode) and the MDIP ullup resistor should be placed as close as
possible to the PF15 / PF14 tracks to reduce the effect of a stub on the transmission line.

All Ethernet Signals
are in power domain
VDD_HV_B
The Ethernet
interface only
supports 3.3V
operation. All I/O
signals must be 3.3V.
If VDD_HVA is set to
5V, Ethernet MCU pads
must be left as
tri-state with no
pullups.
