1000BASE-T1 SFP Module H-MTD


Converts between 1000BASE-T1 (automotive Gigabit Ethernet) and SGMII Interface.


The 1000BASE-T1 SFP Module H-MTD is a solution to convert between 1000BASE-T1 and SGMII using an H-MTD connector. It fits into a standard SFP(+) (Small Form-factor Pluggable) slot and provides an Automotive Ethernet interface (100/1000 Mbit/s full-duplex, on one single twisted pair cable). When plugged into approved devices, Hardware-in-Loop (HiL) systems, and test benches with compatible chassis, the SFP Module has to be configured to Automotive Ethernet (100- or 1000BASE-T1) after power-up.

The device features four dip switches for the following functionalities:

Dip switch no. 1: Slave/Master setting

Dip switch no. 2: 100/1000Mbps

Dip switch no. 3: IEEE/Legacy mode

Dip switch no. 4: SingleSendS/MultipleSendS mode

The device can be used together with other Technica Engineering products, like the Media Gateway (LINK) or the Enhanced Ethernet Switch (EES) (LINK), or other approved chassis of Technica partners. However, the SFP Modules do not work as a “plug-and-play” solution. To set up the SFP Module, the user must be able to interact with the registers of the Phy via I²C and get in touch with Marvell (the PHY manufacturer) to receive the NDA-protected PHY-register setting datasheet to initialize the Phy. Some commercially available devices already recognize and work with the SFP modules successfully, please check the supported devices together with us.
