Interfaces and Pins
SFP+ Connector
On the TEBA0841 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).
The RX-/TX-data-lanes are connected to B2B-connector JB2, the control-lines are connected to pins on B2B-connector JB1 and are MIO-pins in standard TE module's pin-assignment.
On this SFP+ connector, on both 4 x 5 SoMs TE0741 and TE0841 MGT-lane 3 is accessible.
The pin-assignment of the SFP connector is in detail as fellows:
| SFP+ pin | SFP+ pin netname | B2B |

Bridged MGT-Lanes on B2B Connector JB2
The TEBA0841 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, the RX/TX differential pairs are bridged, hence the transmitted data on this MGT-lanes are received simultaneously by the same MGT-lane.
The MGT-lane pins are bridged as fellows, if 4 x 5 SoM TE0741 is mounted:
| MGT-lane | B2B TX diff-pair | B2B RX diff-pair | B2B-pins bridged |
|---|---|---|---|
| MGT-lane 0 | JB2-8 (MGT_TX0_N) JB2-10 (MGT_TX0_P) | JB2-7 (MGT_RX0_N) JB2-9 (MGT_RX0_P) | JB2-7 to JB2-8 bridged JB2-9 to JB2-10 bridged |
| MGT-lane 1 | JB2-14 (MGT_TX1_N) JB2-16 (MGT_TX1_P) | JB2-13 (MGT_RX1_N) JB2-15 (MGT_RX1_P) | JB2-13 to JB2-14 bridged JB2-15 to JB2-16 bridged |
| MGT-lane 2 | JB1-20 (MGT_TX2_N) JB1-22 (MGT_TX2_P) | JB1-19 (MGT_RX2_N) JB1-21 (MGT_RX2_P) | JB1-19 to JB1-20 bridged JB1-21 to JB1-22 bridged |
| MGT-lane 7 | JB1-3 (MGT_TX7_P) JB1-5 (MGT_TX7_N) | JB1-9 (MGT_RX7_P) JB1-11 (MGT_RX7_N) | JB1-3 to JB1-9 bridged JB1-5 to JB1-11 bridged |
| MGT-lane 6 | JB1-15 (MGT_TX6_P) JB1-17 (MGT_TX6_N) | JB1-21 (MGT_RX6_P) JB1-23 (MGT_RX6_N) | JB1-15 to JB1-21 bridged JB1-17 to JB1-23 bridged |

Note: The MGT-lanes of 4 x 5 SoM TE0841 have other designations.
USB Interface
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 TEBA0841.
JTAG Interface
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 |
| G (pin 11) | RESIN | JB3-17 |
Table 3: JTAG header JX1 pin-assignment
There is also the option to mount and solder a 2-row 16-pin header to the place-holder J3, which has the same pin-assignment as header JX1, but with also two additional pins (15,16) as LVDS-pair, to put an external reference clock-signal to the mounted 4 x 5 SoM. The clock-signal is put to to the SoM via B2B-connector pins JB2-32 (MGT_CLK0_N) and JB2-34 (MGT_CLK0_P).
On both interfaces (JX1, J3), the pins with the net-names MIO14 and MIO15 are available as user IO's which could be used as UART-interface for example.
LEDs
There are two LEDs D1 (green) and D2 (red) available to the user. The green LED D1 is connected to the pin MIO9 (JB1-92), the red LED D2 is connected to the pin JB3-90 with the net name 'RLED'.
Header place-holder J4
The place-holder J4 with solder-pads to mount a 2-row 10-pin header provides the capability, to access via this header the SDIO-port of the mounted 4 x 5 SoM, if available. For this purpose, there is also voltage-translation via SDIO port expander (e.g. Texas Instruments TXS02612) necessary due to the different voltage levels of the Micro SD Card (3.3V) and MIO bank of the Xilinx Zynq-chip (1.8V).
Header place-holder J17 and J20
The place-holders J17 and J20 with solder-pads to mount 2-row 50-pin headers provide the capability to access the PL IO-bank pins of the mounted 4 x 5 SoM.
With mounted header J17 there are 42 IO's of PL-IO-bank 13 of the 4 x 5 SoM available (B2B-connector JB3), which are also usable as 21 LVDS-pairs. On this header the IO's are operable with fixed (3.3V) or selectable VCCIO-voltage VCCIOD.
On header J20 there are 42 IO's available of PL-IO-bank 35 (B2B-connector JB1). This IO's are also usable as 21 LVDS-pairs and operable with fixed (3.3V) or selectable VCCIO-voltage VCCIOA.
Power
Power Supply
Power supply with minimum current capability of 3A at 12V for system startup is recommended.
Power-On Sequence
The on-board voltages of the carrier board will be powered up simultaneously after one single power-supply with a nominal voltage of 12V is connected to the power-jack J10.
The PL IO-bank supply voltage FMC_VADJ will be available after the output of the 5.0V-DCDC-converter is active and the pin EN_FMC of the SC-CPLD is asserted.
Figure 3: Power-Up sequence diagram
Configuring VCCIO
On the TE0705 carrier board different VCCIO configurations can be chosen by jumper J21 and DIP-switch S3.
The purpose of the jumper and the DIP-switch S3 of the Carrier Board will be explained in the following sections.
Summary of VCCIO-configuration
On the TE0705 carrier board all PL IO-bank's supply voltages of the 4x5 SoM (VCCIOA, VCCIOB, VCCIOC, VCCIOD; see 4x5 Module Integration Guide) are connected to the VCCIO-voltage VIOTB, which is either fixed to 3.3V (J21: 1-2, 3) or selectable with the adjustable supply-voltage VADJ (J21: 1, 2-3). The supply-voltages have following pin-assignments on B2B-connectors:
base-board supply-voltages | base-board B2B connector-pins | standard assignment of PL IO-bank supply-voltages on TE 4x5 module's B2B connectors | base-board voltages and signals connected with |
|---|---|---|---|
| VIOTB | JB1-10, JB1-12, JB2-2, JB2-4, JB2-6, JB2-8, JB2-10 | VCCIOA (JM1-9, JM1-11), VCCIOB (JM2-1, JM2-3), VCCIOC (JM2-5), VCCIOD (JM2-7, JM2-9) | VCCIO3 (Systm-Controller-CPLD pin 5, 11, 23), J15 VTREF, J11, J13, J2, J5 and J6 VCCIO |
Table 4: base-board supply-voltage VIOTB
Note: The corresponding PL IO-voltage supply voltages of the 4x5 SoM to the selectable base-board voltage VIOTB 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 | VIOTB | USB-VBUS |
|---|---|---|
| 3V3 | J21: 1-2, 3 | - |
| VADJ | J21: 1, 2-3 | - |
| 5V0 intern | - | J9: 1-2, 3 & J19: 1-2 (J20: 1-2: additional decoupling-capacitor 100 µF) |
| Vbus extern | - | J9: 1, 2-3 & J19: open |
Table 5: Configuration of base-board supply-voltages via jumpers. Jumper-Notification: 'Jx: 1-2, 3' means pins 1 and 2 are connected, 3 is open. 'Jx: 1, 2-3' means pins 2 and 3 are connected, 1 is open
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.
