3. Ordering Information

The Si530/531 XO supports a variety of options including frequency, temperature stability, output format, and VDD.

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 10 and 11 for the pinout differences between the Si530 and

Si531 series.

Frequency (e.g., 622M080 is 622.080 MHz)

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

1213 to 1417 MHz. The position of M ﺴshifts 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.
