Connectors and Jumper Configurations

FMC Connector

The FMC connector connects to the LPC connector of the carrier board.

RJ45 Connectors

The RJ45 connectors M1 for Channel A and M2 for Channel B have built-in magnetics that help reduce the size of the board. Each is dedicated to a PHY interface (ADIN1300), allowing each channel to operate independently.

Configuration Resistors

MAC Interface

The pins for selecting the MAC interface are shared with the RX_CTL/RX_DV/CRS_DV pin and RXC/RX_CLK pin, which have weak internal pull-down resistors and are configured to RGMII mode with 2ns delay by default. The ADIN1300 MAC interface selection can be done via software but can also be hardware configured upon device power-up using the table below.

Table 1 MAC Interface Selection

MAC Interface Selection	MACIF_SEL1 (Phy A / Phy B)	MACIF_SEL0 (Phy A / Phy B)
RGMII RXC/TXC 2 ns delay	R12 / R78	R9 / R75
RGMII RXC/TXC 2 ns delay	R11 / R77	R9 / R75
MII	R17 / R78	R8 / R74
RMII	R11 / R77	R8 / R74

Configuration Modes

These configuration modes are used to set Auto-MDIX and PHY speed configurations for both PHY channels A and B.

Table 2 Configuration Modes

Mode	R_LO	R_HI
MODE_1	10k	Open
MODE_2	10k	56k
MODE_3	56k	10k
MODE_4	Open	10k

PHY Interface

Both channels are configured upon power-up for:

• 10 Mbps Half/Full Duplex

• 100 Mbps Half/Full Duplex

• 1000 Mbps Full Duplex (Slave mode)

Auto-MDIX

Table 3 Auto-MDIX Configuration

Configuration	MDIX_MODE
Manual MDI	MODE_1
Manual MDIX	MODE_2
Auto MDIX – Prefer MDIX	MODE_3
Auto MDIX – Prefer MDI	MODE_4

LED Indicators

These LEDs indicate when a link is established and blink when there is activity.

• PHY Channel A LED: DS4

• PHY Channel B LED: DS2
