The proFPGA product family is a complete, scalable, and modular multi FPGA solution, which fulfills highest needs in the area of FPGA based Prototyping. Because of its modular and scalable system architecture, the user has maximum flexibility and reusability.

Part of this modular and flexible system concept is the proFPGA DAC Interface board. This daughter board occupies one extension site of the proFPGA system and provides a dual, 16bit digital-to-analog converter (AD9142A, Analog Devices) that supports sample rates up to 1600MSPS. Both DAC outputs are connected via analog filter stages to MMCX connectors. 

A programmable clock generator is available to provide clocks to the DAC and optionally to the FPGA and MMCX connectors. There are also MMCX connectors as a alternative clock input of the clock generator at the board. Each DAC has its own filter stage shown in Figure 146. These stages are identically for each DAC output. The implemented Low pass filter (LFCN-800+, Mini-Circuits) passes frequencies between DC and 800MHz with a maximum insertion loss of 1.3dB through. Its cut-off frequency is 990Mhz.

Part of this modular and flexible system concept is the proFPGA FMC Carrier Card Adapter. This daughter board occupies one extension site of the FMC carrier card and provides a connection between a FMC carrier card and the proFPGA system. It provides 2 proFPGA cable connectors (top-side), 1 FMC HPC (high pin count) connector (bottom side), 40 MMCX connectors for MGT signals (10 MGT RX and TX pairs), 4 MMCX connectors for MGT REFCLK signals (2 MGT Refclk pairs) and 1 PSU for VIO voltage generation of Bank B signals (voltage can be set via jumper). With this daughter card in combination with the proFPGA Interconnection Cables a FMC Carrier Card can easily be connected to the proFPGA system.

Part of this modular and flexible system concept is the proFPGA ADC Interface board. This daughter board occupies one extension site of the proFPGA system and has two 16-bit 250MSPS ADCs (ISLA216P25, Intersil). Each ADC has one channel. The two input channels of the ADCs are connected with an input filtering stage to MMCX connectors. Both ADCs are directly connected to the bottom connector. Each ADC channel has its own analog ground and a shielding. The shielding is removable for customizing the filtering circuit. 

A clock generator is on the board which sources the ADCs and 2 clock outputs. It is possible to work with the same clock for both ADCs or with different clocks. An external clock input is also connected to the clock generator which allows that one or both ADCs are working with the external clock source. An external trigger input is on the board. This port is connected to the proFPGA bottom connector and may be used for event management. The board has a proFPGA top connector which makes unused FPGA connections available to another extension board or a cable.

Part of this modular and flexible system concept is the proFPGA FMC Mezzanine Adapter Board. This daughter board occupies two extension sites of the proFPGA system and provides a HPC (high pin count) connector which is compliant to the FMC standard [FMC] and supports a wide portfolio of FMC Mezzanine boards. It provides 1 FMC connector on the top side, 116 FMC bank A signals (58 differential signals), 44 FMC bank B signals (22 differential signals), 2 differential unidirectional clk signals, 2 differential bidirectional clk signals, 2 differential REFCLK signals for MGTs and 10 differential MGT signals (10 RX and 10 TX).
