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.

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:

JTAG Signal	B2B Connector	12-pin header JX1
TMS	JB2-94	12
TDO	JB2-98	8
TDI	JB2-96	10
TCK	JB2-100	4

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:

PHY	B2B-pin	Notes
MDC/MDIO	JB3-49, JB3-51	-
LED0	-	Connected to Ethernet jack J2 LED0 (green).
LED1	-	Connected to Ethernet jack J2 LED1 (green).
INT	JB3-33	-
CONFIG	JB3-60	-
RESET	JB3-53	-
RGMII	JB3-37 - JB-44, JB3-47, JB3-57 - JB-59	12 pins.
SGMII	-	Not connected.
MDI	-	Connected to Gigabit-Ethernet MagJack J2.

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.

Note: Pin OTG-ID is only assigned to USB 2.0 type B socket.

DIP switch S1

Switch	Signal Name	ON	OFF	Notes
S1-1	-	-	-	Not connected
S1-2	PROGMODE	JTAG enabled for programing SoM FPGA	JTAG enabled for programing SoM CPLD	-
S1-3	MODE	Drive SoM SC CPLD pin 'MODE' low	leave SoM SC CPLD pin 'MODE' open	Boot mode configuration, if supported by SoM. (Depends also on SoM SC CPLD firmware).
S1-4	EN1	Drive SoM SC CPLD pin 'EN1' low	drive SoM SC CPLD pin 'EN1' high	Usually used to enable/disable FPGA core-voltage supply. (Depends also on SoM SC CPLD firmware). Note: Power-on sequence will be intermitted when S1-4 is set to OFF and functionality is supported by SoM.

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

Power Input Pin	Max Current
VIN	4A

Typical power consumption for TE0706-02 in conjunction with different 4x5 SoMs under certain configurations will be determined soon.

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.

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.

VCCIO voltage selection jumpers J10, J11 and J12

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

Baseboard supply voltage	Baseboard B2B connector pins	Standard assignment of PL I/O bank supply voltages on TE 4x5 module's B2B connectors
VCCIOA	JB1-10, JB1-12	VCCIOA (JM1-9, JM1-11)
VCCIOB	JB2-6	VCCIOC (JM2-5)
VCCIOC	JB2-8, JB2-10	VCCIOD (JM2-7, JM2-9)
Fixed 1.8V	JB2-2, JB2-4	VCCIOB (JM2-1, JM2-3)

Note: The corresponding PL I/O bank supply voltages of the 4x5 SoM to the selectable baseboard voltages VCCIOA, VCCIOB and VCCIOC are depending on the mounted 4x5 SoM and varying in order of the used model.

Refer to the SoMs schematic for information about the specific pin assignments on module's B2B-connectors regarding the PL I/O bank supply voltages and to the 4x5 Module integration Guide for VCCIO voltage options.

Following table describes how baseboard supply voltages VCCIOA, VCCIOB, VCCIOC and 1.8V are connected to the PL I/O bank voltages on different supported 4x5 SoMs:
