Clocking

Si5338 programmable clock generator is used to generate different clocks with 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 can be programmed to change the output frequency of the FPGA clocks (the Ethernet clock must remain at 50 MHz). An I2C bus is connected between the FPGA (master) and clock generator (slave). Proper logic needs to be created in the FPGA to exercise the I2C bus with the correct data. See the reference design section for more information.

Certain B2B connector pins are connected to the FPGA pins which are capable of handling clocking signals from the user’s PCB (baseboard). See schematics B2B page for additional information.

On-board Peripherals

32 MByte Quad SPI Flash Memory

On-board QSPI flash memory S25FL256S (U14) is used to store initial FPGA configuration. Besides FPGA configuration, remaining free flash memory can be used for user application and data storage. All four SPI data lines are connected to the FPGA allowing x1, x2 or x4 data bus widths. Maximum data rate depends on the selected bus width and clock frequency used.

SPI Flash QE (Quad Enable) bit must be set to high or FPGA is unable to load its configuration from flash during power-on. By default this bit is set to high at the manufacturing plant.

System Controller CPLD

System Controller CPLD (Lattice MachXO2-256HC, U3) is used to control FPGA configuration process. The FPGA is held in reset (by driving the PROG_B signal low) until all power supplies have stabilized.

By driving signal RESIN to low you can reset the FPGA. This signal can be driven from the user’s baseboard PCB via the B2B connector JM2 pin 18.

Input EN1 is also gated to FPGA reset, should be open or pulled up for normal operation. By driving EN1 low, on-board DC-DC converters will be not turned off.

User can create their own System Controller design using Lattice Diamond software. Once created it can be programmed into CPLD via JTAG interface.

DDR3 SDRAM

The TE0712-02 SoM has two 4 Gbit volatile DDR3 SDRAM ICs (U15 and U19) for storing user application code and data.

  • Part number: IM4G16D3FABG-125I
  • Supply voltage: 1.5V
  • Organization: 32M words x 16 bits x 8 banks
  • Memory speed: limited by Xilinx Artix-7 speed grade and MIG

 Configuration of the DDR3 memory controller in the FPGA should be done using the MIG tool in the Xilinx Vivado Design Suite IP catalog.

Ethernet PHY

The 10/100 Mbps Ethernet PHY TLK106 (U5) by Texas Instruments is connected to the FPGA bank 14 using Reduced Media Independent Interface standard (RMII). The RMII standard has reduced set of data lines (two rather than four) and a higher clock frequency (50 MHz rather than 25 MHz) compared to the Media Independent Interface standard (MII). A management interface is also available allowing access to registers in the PHY chip. Transmit and receive signals are connected to the B2B connector JM1. The magnetics and RJ-45 jack must be placed on the user's PCB (baseboard).

All signals are connected to the FPGA bank 14 and correspond to LVCMOS33 standard.

MAC Address EEPROM

TE0712-02 module has a 2 Kbit Serial Electrically Erasable PROM (EEPROM, U7).  It provides pre-programmed 48-bit Extended Unique Identifier (EUI-48™) to identify network hardware MAC address which is write-protected to ensure tamper-proof designs. This SEEPROM can be accessed by UNI/O® serial interface bus using Manchester encoding techniques. The clock and data are combined into a single, serial bit stream (SCIO), where the clock signal is extracted by the receiver to correctly decode the timing and value of each bit. The bus is controlled by a master device (Xilinx Artix-7) which determines the clock period, controls the bus access and initiates all operations, while the SEEPROM works as a slave. Refer to Microchip's 11AA02E48 datasheet for more information.

Power and Power-On Sequence

Power Supply

Single 3.3V power supply (for both VIN and 3.3VIN power rails) with minimum current capability of 3A for system startup is recommended.

Power Consumption

Typical module power consumption is between 2-3W. Exact power consumption is to be determined.

TE0712-02 module can also be powered by split 5V/3.3V power sources if preferred. In such case apply 5V to B2B connectors VIN pins and 3.3V to 3.3VIN pins, although lowest power consumption is achieved when powering the module from single 3.3V supply. When using split 5V/3.3V supplies the power consumption (and heat dissipation) will rise due to the DC-DC converter efficiency (it decreases when VIN/VOUT ratio rises).

Power-On Sequence

For the highest efficiency of the on-board DC-DC regulators, it is recommended to use same 3.3V power source for both VIN and 3.3VIN power rails. Although VIN and 3.3VIN can be powered up in any order, it is recommended to power them up simultaneously.

It is important that all baseboard I/Os are 3-stated at power-on until 3.3V is present on B2B connector JM2 pins 10 and 12, meaning that all on-module voltages have become stable and module is properly powered up.

See Xilinx datasheet DS181 - "Artix-7 FPGAs Data Sheet: DC and AC Switching Characteristics" for additional information. User should also check related baseboard documentation when choosing baseboard design for TE0712 module.

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.
