3. Ordering Information
The Si590/591 XO supports a variety of options including frequency, temperature stability, output format, and V
Specific device configurations are programmed into the Si590/591 at time of shipment. Configurations can be
specified using the Part Number Configuration chart below. Silicon Laboratories provides a web browser-based
part number configuration utility to simplify this process. Refer to
tool and for further ordering instructions. The Si590 and Si591 XO series are supplied in an industry-standard,
RoHS compliant, 6-pad, 5 x 7 mm package. The Si591 Series supports an alternate OE pinout (pin #1) for
LVPECL, LVDS, and CML output formats. See Tables 8 and 9 for the pinout differences between the Si590 and
Si591 series.
