Specific device configurations are programmed into the Si534 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 Si534 is supplied in an industry-standard, RoHS compliant, 6-pad, 5 x 7 mm
package.

6-digit Frequency Designator Code
Four 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 quad XOs
programmed with the lowest frequency value selected when
FS[1:0] = 00, and the highest value when FS[1:0] = 11. Six digit
codes < 000100 refer to quad XOs programmed with the highest
frequency value selected when FS[1:0] = 00, and the lowest value
when FS[1:0] = 11.

Example Part Number: 534AB000108DGR is a 5 x 7 mm quad XO in a 8 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 3.3 V supply, LVPECL output, and Output
Enable active high polarity. 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.
