Product Summary

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.
