Purchase your RDDRONE-T1ADAPT: Ethernet media converter

1. Out of the Box

The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost, and improved performance in powering state-of-the-art systems.

This page will guide you through the process of setting up and using the RDDRONET1ADAPT evaluation board.

2.2 Board Description

The RDDRONE-T1ADAPT Ethernet adapter board is an evaluation platform for automotive 100BASE-T1 Ethernet. It can be used to connect a standard 100BASE-TX Ethernet device, such as a PC or single-board computer, to a peripheral device with a T1 Ethernet interface. Two RDDRONE-T1ADAPT boards can be used to connect two standard Ethernet devices together via a T1 network.

Software source code is available on request if the user wants to modify the configuration. However, the board is designed for plug-and-play out of the box with no additional software needed.

2.3 Board Components

Figure 1.RDDRONE-T1ADAPT board

Label	Name	Description
1	TJA1101	The TJA1101 100BAE-T1 automotive Ethernet PHY from NXP Semiconductors is used to support the T1 side of the media converter
2	100BASE-TX PHY	The third party 10/100BASE-TX Ethernet PHY supports the standard Ethernet side of the media converter
3	LPC812	The ARM Cortex-M0 micro is used to configure the two back-to-back PHYs and to control the master/slave behavior of the TJA1101
4	Debug connector	This debug interface can be used to program the device. Since a physical connector is not mounted on the board, a cable such as the TC2050-ID-NL can be used to interface with the board via the debug interface.

3. Configure Hardware

The RDDRONE-T1ADAPT board is designed to interface between standard 100BASETX Ethernet and two-wire automotive Ethernet in order to evaluate T1 performance. A number of configuration options are possible.

3.1 Evaluate T1 Between Two 100BASE-TX Devices

A pair of RDDRONE-T1 boards are used to connect two standard PCs with RJ45 connectors together over a 2-wire T1 network. The adaptors communicate with each other via T1 and the power is supplied by the PCs over USB cables.

3.2 Evaluate Communication Between a TX and a T1 Device

An RDDRONE-T1ADAPT is used to connect a PC or single-board computer to a T1 peripheral. In this configuration, the power may be supplied through the 3-pin JST-GH connector with 5.0 V power coming from a pin header or matching connector on the single-board computer.
