Simplifying Power Supply Design in FPGA-based Systems
FPGA-based systems have become common and are appropriate for many applications. However, by their nature, FPGAs are power-hungry devices with complex power delivery requirements and multiple voltage rails. When FPGA power consumption increases, performance requirements on sensitive analog and mixed signal subsystems also increase, particularly on clocking subsystems that provide low jitter timing references for the FPGA and other board-level components. By using clock sources with integrated power supply noise rejection, designers can simplify power supply design and mitigate these design challenges.
