Description
J1 Jumper for board power selection.
J2, J3 Jumpers for local power: 3.3 V and 1.8 V. Keep J2 and J3 inserted.
S201 ADIN1100 hardware configuration. See the ADIN1100 data sheet for descriptions of all options (on: high, pull-up resistor).
S501 EVAL-ADIN1100EBZ board reset button. Reset the board after any configuration change.
S403 Microcontroller configuration switch (labeled uC CFG) media converter. Mode 15: all off (see Table 6 ).
LED400 to LED403 Microcontroller LEDs (labeled uC0 to uC3).
uC0 (green) for media converter (on: both links are up).
uC1 (red) for error (on: system error).
uC2 (orange) for microcontroller heartbeat (blinking: microcontroller is active).
uC3 (blue) is reserved for future use or user functions.
P1, P2 Connectors for external board power supply, 5 V dc to 32 V dc. If the board is supplied from a USB, the external power is disabled.
LED_0, LED_1 ADIN1100 status. LED_0 gives link or activity status. LED_1 is on when the 2.4 V transmit level amplitude is used and off when the 1.0 V
transmit level amplitude is used.
10BASE-T1L Shield for 100 W twisted single pair Ethernet cable.
J101 Jumper for 10BASE-T1L able Shield. Connected to Earth directly or via a 4000 pF capacitor.
Mounting Hole 3.2 mm for M3 screw, Earth ground for electromagnetic compatibility (EMC).
Micro USB Connector For use of the EVAL-ADIN1100EBZ board with PC GUI software or USB COM port to host terminal software: 115,200 baud rate, 8-bit, no
parity, one stop bit. The board can receive power from a USB port or charger.
P501 Connector for MDIO. P501 can be used for managing external PHYs using the on-board microcontroller and related software. The
on-board PHYs can be managed by an external host. In this case, keep the local microcontroller in reset by placing Jumper J401 in
Position GND.
P5 RJ45 10BASE-T Ethernet connector for autonegotiation, advertising 10 Mb full duplex as the only option to link and operate. 10BASE-T1L
is 10 Mb full duplex. The ADIN1100 acts as a media converter and does not buffer data.
RJ45 LEDs that give ADIN1200 status. Yellow: activity; green: link is up.
GND Test points for oscilloscope probe or multimeter ground.
J204, J203, J402 Jumpers for chip power selection. Set ADIN1100 VDDIO = ADIN1200 VDDIO = the microcontroller power (J402).
P201 Header for digital signal access: MII, RMII, RGMII, MDIO, reset, clocks, LEDs, status, and interrupts.
J301 Jumper for ADIN1200 (force) hardware reset. If not using the media converter function, insert this jumper to keep the ADIN1200 in reset
and release its digital signals. The ADIN1100 MII, RMII, or RGMII on Header P201 can then be used safely with the ADIN1200 held in
reset.
