The Trenz Electronic TEC0330 FPGA board is a PCI Express form factor card (PCIe 2.0 or higher) integrating the Xilinx Virtex-7 XC7VX330T FPGA chip. This high-end FPGA card is designed for maximum system performance and intended for use in applications with high demands on system throughput. There is a SO-DIMM socket on the board for standard DDR3 SDRAM extension memory module.

Signals, Interfaces and Pins

FMC Connector

The high-pin count (HPC) FMC (FPGA Mezzanine Card) connector (J2) is a standard ANSI/VITA 57.1 modular interface to the FPGA and provides access to numerous FPGA I/O pins for use by other mezzanine modules and expansion cards. The FMC connector supports single ended I/O (with several VCCIO voltages available) and LVDS I/O signaling.

The I/O signals are routed from the FPGA I/O banks to the FMC connector as LVDS pairs:

Bank 19	92	46	1.8V	-
Bank 39	42	21	VIO_B_FMC	Bank voltage VIO_B_FMC must be supplied by FMC connector pins J2-J39, J2-K40. Bank's VREF_B_M2C signal is routed to the FMC connector pin J2-K1 (external reference voltage).
Bank 37	34	17	1.8V	Bank's VREF_A_M2C signal is routed to the FMC connector pin J2-H1 (external reference voltage).

On-board Peripherals

System Controller CPLD

The System Controller CPLD is the central system management unit that provides numerous interfaces between the on-board peripherals and to the FPGA module. The signals routed to the CPLD will be linked by the logic implemented in the CPLD firmware, which generates output signals to control the system, the on-board peripherals and the interfaces. So some interfaces between the on-board peripherals and to the FPGA module are by-passed, forwarded and controlled by the System Controller CPLD.

Other tasks of the System Controller CPLD are the monitoring of the power-on sequence, the proper programing of the FPGA module and to display its programming state.

SO-DIMM Socket for DDR3 SDRAM

The TEC0330 board supports additional DDR3 SO-DIMM via 204-pin SO-DIMM socked U2. The DDR3 memory interface is routed to the FPGA banks 34, 35 and 36.

The reference clock signal for the DDR3 interface is generated by the quad programmable reference clock U13 and is applied to bank 35.

There is also a I²C interface between the System Controller CPLD and the DDR3 SDRAM memory:

DDR3_SDA	Bank 2, pin 48	Pin 200 (3V3PCI pull-up)
DDR3_SCL	Bank 2, pin 49	Pin 202 (3V3PCI pull-up)

Table 13: I²C-interface between SC CPLD and DDR3 SDRAM memory.

Quad SPI Flash Memory

An 256 Mbit (32 MByte) Quad SPI Flash Memory (Micron N25Q256A, U12) is provided for FPGA configuration file storage. After configuration process completes the remaining free memory can be used for application data storage. All four SPI data lines are connected to the FPGA allowing x1, x2 or x4 data bus widths to be used. The maximum data transfer rate depends on the bus width and clock frequency. The memory can be accessed indirectly by the FPGA JTAG port (J9) by implementing the functional logic for this purpose inside the FPGA.

Clock sources

The TEC0330 FPGA board has a sophisticated clock generation and conditioning system to meet the requirements of the Xilinx Virtex-7 GTH units with data transmission rates up to 13.1 Gb/s.

Programmable Clock Generator

There is a Silicon Labs I²C programmable quad clock generator Si5338A (U13) on-board. It's output frequencies can be programmed by using the I²C-bus with address 0x70.

A 25 MHz (U14) oscillator is connected to pin 3 (IN3) and is used to generate the output clocks.

Once running, the frequency and other parameters can be changed by programming the device using the I²C bus connected between the FPGA (master) and clock generator (slave). Logic needs to be generated inside the FPGA module to utilize I²C-bus correctly.

Ultra low-noise high-performance clock synthesizer

The TEC0330 board utilizes an ultra low jitter clock synthesizer TI LMK04828B (U9) for conditioning and generating clean clock signals which are necessary for the GTH units of the Xilinx Virtex-7 FPGA module.

The clock synthesizer can be controlled and programmed by its SPI interface (SPI slave) and other control lines, which are routed to the FPGA module (SPI master) and by-passed trough the System Controller CPLD. See section 'System Controller CPLD' for more detailed information.

Logic needs to be generated inside the FPGA module to utilize SPI bus correctly.

Power and Power-On Sequence

Power Supply

6-pin 12V power connector J5 is the main power supply of the TEC0330 FPGA board, minimum current capability of 3A for system startup is recommended.

Power Consumption

Power Input	Typical Current
12V (J5)	TBD
3V3PCI (J1)	TBD

Table 17: Typical power consumption. TBD - To Be Determined.

Power-On Sequence

The on-board voltages of the TEC0330 FPGA board will be powered up in order of a determined sequence after the external voltages 12V on connector J5 and 3V3PCI on connector J1 are available.

Core voltages and main supply voltages have to reach stable state and their "Power Good"-signals have to be asserted before other voltages like PL bank's I/O voltages can be powered up.

Following diagram describes the sequence of enabling the on-board voltages:

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.
