Further information and related links

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 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.
