SFP+ Connector
On the The TEBB0714 Carrier Board is there provides a SFP+ connector J1 (Molex 74441-0001 ( at board-rev. 01 ). The connector is embedded into a SFP cage J2 (Molex 74737-0009 ( at board-rev. 01 ).
The RX- / TX-data-lanes are connected to B2B-connector JB2JM1, the control-lines are connected to pins on B2B-connector JB1 and are MIO-pins in standard TE module's pin-assignment.

The JTAG-interface of the mounted 4 x 5 SoM can be accessed via header JX1. This header has a 'XMOD FTDI JTAG Adapter'-compatible pin-assignment.
| JX1 pin | JX1 pin net-name | B2B |
|---|---|---|
| C (pin 4) | TCK | JB3-100 |
| D (pin 8) | TDO | JB3-98 |
| F (pin 10) | TDI | JB3-96 |
| H (pin 12) | TMS | JB3-94 |
| A (pin 3) | MIO15 | JB1-86 |
| B (pin 7) | MIO14 | JB1-91 |
| E (pin 9) | BOOTMODE | JB1-90 (JTAGSELECT) |
| G (pin 11) | RESIN | JB3-17 |

On the TEBA0841 carrier board the PL IO-bank's supply voltages of the 4x5 SoM (VCCIOA, VCCIOD; see 4x5 Module Integration Guide) are connected to the base-board VCCIO-voltage VCCIOA and VCCIOD, which are selectable between the supply-voltages 1.8V, 2.5V and 3.3V via jumper J26 and J27.
baseboard supply-voltages | base-board B2B connector-pins | standard assignment of PL IO-bank supply-voltages on TE 4x5 module's B2B connectors-pins |
|---|---|---|
| VCCIOA | JB1-10, JB1-12 | VCCIOA (JM1-9, JM1-11) |
| VCCIOD | JB2-8, JB2-10 | VCCIOD (JM2-7, JM2-9) |
Table 5: base-board supply-voltages VCCIOA and VCCIOD
| Note |
|---|
Note: The corresponding PL IO-voltage supply voltages of the 4x5 SoM to the selectable base-board voltage VCCIOA and VCCIOD are depending on the mounted 4x5 SoM and varying in order of the used model. Refer to SoM's schematic to get information about the specific pin-assignment on module's B2B-connectors regarding PL IO-bank supply-voltages and to the 4x5 Module integration Guide for VCCIO voltage options. |
Following table describes how to configure the base-board supply-voltages by jumpers:
base-board supply-voltages vs voltage-levels | VCCIOA | VCCIOD |
|---|---|---|
| 1.8V | J26:1-2 | J27:1-2 |
| 2.5V | J26:3-4 | J27:3-4 |
| 3.3V | J26:5-6 | J27:5-6 |
Table 6: Configuration of base-board supply-voltages via jumpers. Jumper-Notification: 'Jx: 1-2' means pins 1 and 2 are connected, 'Jx: 3-4' means pins 3 and 4 are connected, and so on.
| Note |
|---|
| It is recommended to set and measure the PL IO-bank supply-voltages before mounting of TE 4x5 module to avoid failures and damages to the functionality of the mounted SoM. |
