The ADTJA1101-RMII adapter board evaluates the NXP part TJA1101, including all functions. The board features the following:
The ADTJA1101-RMII board is an easy-to-use adapter board, allowing the user to add 100BASE-T1 automotive Ethernet connectivity to host controllers on compatible controller cards. The TJA1101 PHY transceiver is mounted to the adapter card and connects to the RMII interface of the host controller via SABRE connector.
Power supply and component configuration are provided and managed by the microcontroller (MCU) on the host evaluation board. The ADTJA1101-RMII connects to link partners via an automotive grade unshielded twisted-pair cable.
The ADTJA1101-RMII adapter board features the TJA1101, an IEEE 100BASE-T1 compliant Ethernet PHY. This adapter board is used with a host controller board, like SK32148EVB, or other optional support boards.
Refer to ADTJA1101-RMII - User Guide user manual for additional details on the featured components.
The ADTJA1101-RMII connects to the S32K148 evaluation board using the SABRE connector J1 on the bottom of the board.
The S32K148 evaluation board was chosen specifically to work with the ADTJA1101- RMII kit because it is a low-cost evaluation platform and development system for quick application prototyping and demonstration of the S32K148 MCU belonging to the S32K series of ultra-reliable microcontrollers.
Additional configurations for the ADTJA1101-RMII connected to the SJA1105Q-EVB and the SJA1105SMBEVM are illustrated in the ADTJA1101-RMII User Manual.
To configure the ADTJA1101-RMII for use with the S32K148, complete the following procedure:
Refer to ADTJA1101-RMII - User Guide user manual for additional details on the hardware configuration.
To use the card in the context of TC10 starter kit configuration, the following components are required: up to four satellite nodes, consisting of S32K148EVB and ADTJA1101-RMII adapter card, can be connected to a central node: the SJA1105SMBEVM Gateway Prototyping Platform. These components, allow the user to quickly bring up system level sleep and wake-up forwarding scenarios, which are predefined and ready to load from the software development kit of S32K148EVB.
The TC10 starter kit demonstrates the OPEN Alliance TC-10 compliant wake-up and sleep capabilities of the 100BASE-T1 PHY products TJA1101 and TJA1102. It also provides different ways to exploit these capabilities in own implementations and provides the hardware test bed for prototypical implementations.
When using the TC10 starter kit configuration, refer to the AH1805TC10 Starter Kit Application Hint. The application hint explains how to setup a system to evaluate the TJA1101 and TJA1102 product features in a system context.
AH1805 also explains the usage for predefined software examples, which are available with the Software Development Kit (SDK) of the respective host controller.
The configuration of ADTJA1101-RMII is handled by the host controller on the mated evaluation board.
First, download and run the SDK for the selected host controller (for example, S32K148EVB SDK).
The full TJA110x driver set is supported by the S32K148EVB Software Development Kit (SDK).
This section describes the driver selection for TJA110x.
