Overview

Refer to https://shop.trenz-electronic.de/en/Download/?path=Trenz_Electronic/carrier_boards/TE0706 for downloadable version of this manual and additional technical documentation of the product.

The Trenz Electronic TE0706 is a baseboard intended for use with 4x5 SoMs manufactured by the company. Baseboard exposes MIO- and PS/PL-pins of the SoM to accessible connectors and provides a whole range of on-board components for SoMs evaluation and testing.

See page "4x5 cm carriers" for information about the SoMs supported by the TE0706.

Initial Delivery State

Board is shipped in following configuration:

• VCCIO voltage selection jumpers are all set to 1.8 V.
• S2 switch configured as reset button.
• One VG96 backplane connector is not soldered to the board, but is included in the package as separate component.

Different delivery configurations are available upon request.

Signals, Interfaces and Pins

Board to Board (B2B) I/Os

For detailed information about the B2B pin out, please refer to the Master Pin-out Table. 

JTAG Interface

JTAG access to the SoMs Xilinx Zynq chip on the SoM is provided via 12-pin header JX1 and controlled by DIP switch S1-2. JTAG pins are routed to the JB2 and JX1 connectors as follows:

Micro SD Card Socket

Micro SD Card socket is not directly wired to the B2B connector pins, but through a Texas Instruments TXS02612 SDIO port expander, which is needed for voltage translation due to the different voltage levels of the Micro SD Card and MIO bank 501 of the Xilinx Zynq 7000 chip. The Micro SD Card has 3.3 V signal voltage-level, but the MIO Bank 501 on the Xilinx Zynq 7000 chip is set to 1.8 V.

Ethernet

The TE0706-02 is equipped with a Marvell Alaska 88E1512 Gigabit Ethernet PHY (U6) connected to the B2B connector JB3. The I/O Voltage is fixed at 1.8V. The reference clock input of the PHY is supplied by on-board 25MHz oscillator (U7).

PHY (U6) interface connections: 

RJ45 Gigabit Ethernet MagJack J3

The TE0706-02 carrier board is also equipped with a second Gigabit-Ethernet MagJack J3, which is connected via MDI to the B2B connector JB1.

There is usually a corresponding Gigabit Ethernet PHY on 4x5 SoMs (e.g. TE0715 or TE0720), which can be used in conjunction with the baseboard MagJack J3.

USB Interface

TE0706-02 board has one physical USB type A socket J7 routed to B2B connector JB3. The corresponding USB-transceiver on 4x5 SoMs varies in order of the used SoM model. 

There is also the option to equip a micro USB 2.0 type B receptacle socket (J8) to the board as alternative.

DIP switch S1

Power and Power-On Sequence

Power supply with minimum current capability of 3A for system startup is recommended.

Power Supply

TE0706-02 needs one single power supply with nominal of 5V.

Power Consumption

The power-consumption of TE0706-02 in conjunction with different 4x5 SoMs under certain configurations are depending on the used model of the 4x5 SoM and the custom-made FPGA-design on this SoM. Please refer to the TRM of the mounted 4x5 SoM to get information about the typical power consumption.

Power-On Sequence

It is not allowed to feed any voltage to any external I/O pin before there is no power indication on M3.3VOUT pins. Presence of 3.3V on B2B JB2 connector pins 9 and 11 indicates that module is properly powered up and ready. The 1.8V voltage-level on base-board for supplying  PL I/O bank supply-voltages will be available after the module's 3.3V voltage-level has reached stable state on the B2B JB2 connector pins 9 and 11.

If VCCIOA or VCCIOC  will be powered through the dedicated pins of external connector J6, then corresponding VCCIO jumpers J10 and J12 should be removed.

Base-board supply-voltage configuration

Refer to the 4x5 Module Integration Guide for VCCIO voltage options.

Base-board supply-voltages (VCCIOA, VCCIOB, VCCIOC) selection-jumpers.

Following table shows how to configure the voltage-levels of base-board supply-voltages VCCIOA, VCCIOB and VCCIOC by jumper, 0-Ohm-resistor or by feeding the supply voltage through connector J6:

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.

Only one supply-source is allowed to configure the base-board supply-voltages, either by jumper, by 0-Ohm-resistor or by connector J6. If a supply-voltage is configured by 0-Ohm-resistor or connector J6, then the corresponding configuration-jumper has to be removed. There aren't 0-Ohm-resistors and supply-voltages by connector J6 allowed if the corresponding base-board supply-voltage is configured by jumper. Vice versa jumpers and 0-Ohm-resistors have to be removed if supplying corresponding base-board supply-voltage by connector J6.

Note: If supplying base-board supply-voltages by connector J6, the module's internal 3.3V voltage-level on pins 9 and 11 of B2B-connector JB2 has to be reached stable state.
