SFP+ Connector

On the TEBA0841 Carrier Board carrier board is a SFP+ connector J1 (board-rev. 01: Molex 74441-0001). The connector is embedded into a SFP cage J2 (board-rev. 01: Molex 74737-0009).

Looped-backed MGT-Lanes on B2B Connector JB1 and JB2

The TEBA0841 Carrier Board carrier board is mainly for the 4 x 5 SoMs TE0841 and TE0741. This SoMs have GTX-Transceiver units on their FPGA-modules with up to 8 available MGT-lanes. To test this MGT-lanes, 5 RX/TX differential pairs are bridged on-board, hence the transmitted data on this MGT-lanes flows back to their sources in a loop-back circuit without intentional processing or modification.

The TEBA0841 carrier board has one physical USB-connector J10, which is available as Micro-USB port. The USB interface J10 can be operated in Device- and OTG-modes. The Micro-USB port-pins are routed to the USB-OTG-interface on B2B-connector JB2. There are usually corresponding USB-PHYs on SoMs supported by the Carrier Board carrier board TEBA0841.
