3. Ordering Information
The Si533 XO supports a variety of options including frequency, temperature stability, output format, and V_DD.
Specific device configurations are programmed into the Si533 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 Si533 is supplied in an industry-standard, RoHS compliant, 6-pad, 5 x 7 mm
package. The Si533 supports output enable (OE) on pin 1.

6-digit Frequency Designator Code
Two unique frequencies can be specified within the following bands
of frequencies: 10 to 945 MHz, 970 to 1134 MHz, and 1213 to 1417
MHz. A six digit code will be assigned for the specified
combination of frequencies. Codes > 000100 refer to dual XOs
programmed with the lower frequency value selected when FS = 0,
and the higher value when FS = 1. Six digit codes < 000100 refer to
dual XOs programmed with the higher frequency value selected
when FS = 0, and the lower value when FS = 1.

Example Part Number: 533AB000108DGR is a 5x7mm Dual XO in a 6 pad package. Since the six digit code (000108) is > 000100,
f0 is 644.53125 MHz (lower frequency) and f1 is 693.48299 (higher frequency), with a 3.3V supply and LVPECL output. Temperature
stability is specified as ± 20 ppm. The part is specified for a -40 to +85 C° ambient temperature range operation and is shipped in tape
and reel format.
