3. Ordering Information
The Si590/591 XO supports a variety of options including frequency, temperature stability, output format, and VDD.
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 www.silabs.com/VCXOPartNumber to access this
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.

Frequency (e.g., 148M352 is 148.352 MHz)
Available frequency range is 10 to 525 MHz. The position of “M” shifts
to denote higher or lower frequencies. If the frequency of interest
requires greater than 6 digit resolution, a six digit code will be
assigned for the specific frequency.
