3. Ordering Information
The Si515 supports a variety of options including frequency, stability, tuning slope, output format, and V_DD. Specific
device configurations are programmed into the Si515 at time of shipment. Configurations are specified using the
Part Number Configuration chart shown below. Silicon Labs provides a web browser-based part number
configuration utility to simplify this process. Refer to www.silabs.com/VCXOPartNumber to access this tool. The
Si515 VCXO series is supplied in industry-standard, RoHS compliant, lead-free, 3.2 x 5.0 mm and 5 x 7 mm
packages. Tape and reel packaging is an ordering option.

Figure 2. Part Number Convention
Example ordering part number: 515BBB212M500BAGR.
The series prefix, 515, indicates the device is a single frequency VCXO.
The 1st option code B specifies the output format is LVDS and powered from a 3.3 V supply. The stability and APR
code B indicates a temperature stability of ±20 ppm with a tuning slope of ±120 ppm/V. The 3rd option code B
specifies the OE pin is active low.
The frequency code is 212M500. Per this convention, and as indicated by the part number lookup utility at
www.silabs.com/VCXOpartnumber, the output frequency is 212.5 MHz. The package code B refers to the
3.2 x 5 mm footprint with six pins. The last A refers to the product revision, G indicates the temperature range (–40
to +85 °C), and R specifies the device ships in tape and reel format.
Note: CMOS and Dual CMOS maximum frequency is 212.5 MHz.
