Ordering Information
The Si500D supports a variety of options including frequency, output format, supply voltage, and tri-
state/powerdown. Specific device configurations are programmed into the Si500D at time of shipment.
Configurations are specified using the figure below. Silicon Labs provides a web-based part number utility that can
be used to simplify part number configuration. Refer to www.silabs.com/XOPartNumber to access this tool. The
Si500D XO series is supplied in a ROHS-compliant, Pb-free, 6-pad, 3.2 x 4.0 mm package. Tape and reel
packaging is available as an ordering option.
