Power Rail Design



Individual Power Rail Selection

Use Xilinx's Power Estimator spreadsheet to get a list of all power supply rails and a rough estimate of the current consumption for each. Xilinx also provides XPower tools built into their ISEM design environment that provide a more accurate power requirement based on resource utilization, clock frequency, and toggle rates. Click within the following selector tables to view recommended regulators for your rail:

Low Noise MGT Rails
Powering a multi-gigabit transceiver (MGT) rail requires special design considerations due to requirements for very low ripple and noise (10mV peak-to-peak maximum).

Noise/ripple is not specified in a regulator datasheet. Meeting a noise/ripple spec is achieved through multiple means–for example, board layout, control architecture, and external components.  Any analog PWM controller/regulator that operates in fixed frequency, PWM mode all the time (no skip mode)  is a good candidate for driving an MGT power rail.   LDOs also generally meet the MGT rail noise/ripple specification.

Select a product from the table above to find regulators to power MGT rails. Be sure to take note of the special design considerations for ripple/noise in layout and component selection.
