EVAL-CN0506-FMCZ Hardware User Guide

The CN0506 shown in Figure 1 is a dual channel, low latency, low power Ethernet Phy card supporting speeds of 10/100/1000 Mbps for Industrial Ethernet applications.

The circuit consists of two indivudual, independent 10/100/1000Mb PHYs, each with an energy efficient Ethernet (EEE) physical layer device (PHY) core with all associated common analog circuitry, input and output clock buffering, management interface, subsystem registers, MAC interface and control logic.

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 has built in magnetics that help reduce the size of the the board. Each are dedicated to a phy interface ADIN1300 allowing each channel to be independent.

Configuration Resistors

Mac Interface

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

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

Configuration Modes

These configuration modes are used to set the configurations for Auto MDIX and Phy Speed Configurations for both Phy channels A and B

ModeR_LOR_HI
MODE_110kOpen
Mode_210k56k
Mode_356k10k
Mode_4Open10k

Phy Interface

The board has both of the channels configured for 10 Half Duplex/Full Duplex, 100 Half Duplex/Full Duplex and 1000 Full Duplex slave mode upon power up.

LED Indicators

These LED's indicate when a link is established and is blinking when there is activity. LED on Phy channel A is labelled DS4 and the LED on Phy channel B is labelled DS2.
