Si530/531
3. Ordering Information
The Si530/531 XO supports a variety of options including frequency, temperature stability, output format, and V
.

Specific device configurations are programmed into the Si530/531 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 Si530 and Si531 XO series are supplied in an industry-standard,
RoHS compliant, 6-pad, 5 x 7 mm package. The Si531 Series supports an alternate OE pinout (pin #1) for the
LVPECL, LVDS, and CML output formats. See Tables 9 and 10 for the pinout differences between the Si530 and
Si531 series.

Available frequency range is 10 to 945 MHz, 970 to 1134 MHz, and
1213 to 1417 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.
