This reference design demonstrates an efficient, low-noise five-rail power supply design for very high-speed Data Acquisition (DAQ) systems capable of > 12.8 GSPS. The power supply DC/DC converters are frequency-synchronized and phase-shifted in order to minimize input current ripple and control frequency content. Any potential radiated electromagnetic interference (EMI) is minimized by using high-performance HotRod™ packaging technology.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
