Getting Started with the TJA11xx-SDBx Evaluation Board Family

2.1 Board Features

• Quick functional evaluation of TJA1103 and TJA1104 (100BASE-T1) and TJA1120 and TJA1121 (1000BASE-T1)
• Supports MACsec (TJA1104 and TJA1121)
• Supports MII/RMII/RGMII (PN ending with R)
• Supports SGMII (PN ending with S)
• SMA and JTAG connectors
• Voltage and current tap points
• Control signals accessible via pin headers
• Config pin strapping jumper settings
• Control signals for inhibit and wake in/out
• Multiply supply options

2.2 Board Description

The TJA11xx-SDBx family of evaluation boards is intended to help familiarize the user with TJA1103, TJA1104, TJA1120 and TJA1121 PHYs from NXP. Each of the eight available boards is populated with one of these devices. The SDBR boards support CMOS-based MII, RMII and RGMII MAC interfaces. The SDBS boards feature an SGMII MAC interface.

Configuration options are selected via jumpers. GPIO and control signals are accessible via pin headers for evaluation and debugging purposes. In addition, a number of tap points are provided to enable current and voltage measurements to be taken on the supply rails.

3.1 Install Software

The board can be used on any platform that has a SABRE connector and that supports the required xMII interface. Depending on the use case, the required software can be downloaded from NXP.

• Linux-based platforms: S32Gxx boards/i.MX board - drivers are included in the TJA11xx Linux driver for IEEE 802.3 Clause 45 managed PHYs, which can be downloaded from secure files at the specific PHY product page, for example TJA1103
• Platforms supported by SDK (S32DS): S32K1xx / S32K3xx SDK Real-Time Drivers are included in TJA11XX Ethernet Phy Real-Time Drivers AUTOSAR® 4.4, which can be downloaded from secure files files at the specific PHY product page, for example TJA1103

4.1 Configure Hardware

Before plugging the SDBx board onto a host board, it should be configured as illustrated in Figure 2 and described in Table 1. For this example, the TJA1104-SDBS board has been taken.

Figure 2. TJA1104-SDBS Configuration

Figure 2. TJA1104-SDBS Configuration

Table 1. Quick start settings.

After plugging the SDBx board onto the host board and powering it up, check the following LEDs:

• Green: D5 - on indicates the 3.3 V supply from the host board is active (via the SABRE connector)

Note: D4 indicates the status of the 5 V-12 V supply from the host board (via the SABRE connector); not needed for the quick-start configuration.

• Orange: D10, D11, D13 - indicate supply rail status (1V8, 1V1, 3V3; on = available)

Note: D12 indicates the status of the 3.3 V supply generated by the buck converter from the 5 V-12 V input; not needed for the quick-start configuration.

• Red: D7 - on indicates that the PHY is active (active-HIGH)
• Red: D9 - indicates link status (active-HIGH)
• Red: D3, D8 - reset and wake status (active-LOW, active-HIGH)

If the power indicator LEDs indicate that the board is in the required state, an Ethernet cable and link partner can be connected. If the link partner is active and configured as a responder, a link should be established without the need for software configuration.
