Introduction
NCN26010XMNEVB is a printed circuit board (PCB) designed to
allow customers to evaluate onsemi's NCN26010 SPI-enabled
10Base-T1S transceiver. The NCN26010 integrates both the
physical-layer transceiver (PHY) and media access controller (MAC)
into a "MACPHY" device.
Features
The NCN26010XMNEVB evaluation board (EVB) includes all
circuitry to act as a 10Base-T1S node, when connected to a host
computer / MCU via SPI.
The evaluation board has two RJ45 connectors that allow attaching
a twisted single pair data cable. For ease of use, standard CAT 5
Ethernet cables can be connected to the RJ45 connectors. Note that
only one pair (connected to pin 1 and 2) of the RJ45 connector is used.
Alternatively, terminal blocks or pin headers may be used.
The serial peripheral interface (SPI) of the NCN26010 is routed to a
PMOD connector on the evaluation board, allowing the connection to
micro-controller demonstration and evaluation boards of various
vendors. One example of such a board is onsemi's RSL10
BDK-GEVK.

NCN26010BMNEVB bridge board, users can connect the eval board
to a Raspberry Pi single board computer (SBC). For details on how
this is done, please refer to the NCN26010XMNEVK eval kit users
guide.

To allow monitoring of the SPI traffic, the EVB features a 0.1" pitch
pin header that is easily accessible. This header could also be used to
connect a logic analyser, allowing tracing of the SPI signals while in
full operation together with a Raspberry Pi (not supplied) or any other
suitable host micro-controller or SBC. Users can also use this
connector for connecting to host PCBs (3
boards) that do not offer a PMOD connector.
The evaluation board was revised in 2024. Refer to section
"Revision information" for detailed information.
