The SFP Module 1000BASE-T1 H-MTD allows to extend SGMII capable devices with support for 100/1000BASE-T1-based Automotive Ethernet. It fits into a standard SFP (Small Form-factor Pluggable) slot and provides a H-MTD connector for full-duplex Automotive Ethernet. The device contains a MARVELL 88Q2221M PHY for 100/1000BASE-T1 support.

The SFP Module 1000BASE-T1 H-MTD features DIP switches to define the start-up configuration:

• Dip switch no. 1: Master / Slave setting
• Dip switch no. 2: 100 / 1000 Mbit/s
• Dip switch no. 3: Reserved
• Dip switch no. 4: Reserved

The SFP Module can be easily used together with other Technica Engineering products, like the Switch-based products. For example, it can be plugged into an Enhanced Ethernet Switch to add another 100 / 1000 Mbit/s Automotive Ethernet port.

The SFP Module can also be used with any type of hardware offering a suitable SFP slot, and the SFP Module also offers an I²C to MDIO gateway feature to system integrators that need to extend functionality by directly accessing PHY registers if they desire (TC10 Sleep/Wakeup, MACsec, etc.). It also adds a custom implementation to change the DIP switches default status at run-time so system integrator can change between PHY configurations offered without needing to access the complete technical information from the PHY manufacturer *.

In compliance with SFF-8472 standard the SFP module contains a memory map with device information at I2C address 0xA0, system integrator can identify the TE-1441 device there and create custom implementations. Technica is happy to support the integration with any different customer systems.
