Trenz Electronic TE0712 is a FPGA module integrating an AMD Artix-7 FPGA, with a Quad GTP transceiver, DDR3 SDRAM, QSPI flash memory for configuration and operation. The SoM implements a 10/100 Mbit Ethernet transceiver and powerful switching-mode power supplies for all on-board voltages. All Trenz Electronic SoMs in 4 x 5 cm form factor are mechanically compatible.

The programmable Clock Generator (Si5338A) is used to generate four different clocks from 25 MHz oscillator connected to pin IN3. The Si5338 can alternatively be clocked using pins IN1 and IN2 which are connected to B2B connector JM3 (CLKIN2).
The Si5338 output frequency to the FPGA clocks can be programmed while the Ethernet clock must remain at 50 MHz. An I2C bus is physically connecting the FPGA (master) and clock generator (slave). The I2C logic needs to be created in the FPGA to use this capability. Refer to TE0712 Reference Designs for more information.

These connectors are hermaphroditic. Odd pin numbers on the module are connected to even pin numbers on the baseboard and vice versa.
4 x 5 modules use two or three Samtec Razor Beam LSHM connectors on the bottom side.
When using the same type on baseboard, the mating height is 8mm. Other mating heights are possible by using connectors with a different height

*) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these
or any other conditions beyond those indicated under Recommended Operating Condition. Exposure to absolute-maximum rated conditions for extended periods may affect device reliability.
Trenz Electronic classifies modules into temperature range categories by subsumption of its component data (PCB, ICs, connectors, passive components). The temperature ranges are values for ambient air temperature and do not reflect the junction temperature of individual components.
The categories are:
These categories do not take into account the entire custom system consisting of:
The temperature of individual components should not exceed the specified range due to self-heating or heating by adjacent components.
The actual operating temperature range will depend on the customer design, usage, environment and cooling solution. Consult Cooling Solutions for more information.

WEEE
Information for users within the European Union in accordance with Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 on waste electrical and electronic equipment (WEEE).
Users of electrical and electronic equipment in private households are required not to dispose of waste electrical and electronic equipment as unsorted municipal waste and to collect such waste electrical and electronic equipment separately. By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health. The symbol consisting of the crossed-out wheeled bin indicates separate collection for waste electrical and electronic equipment.
Trenz Electronic is registered under WEEE-Reg.-Nr. DE97922676.
