Si516
3. Ordering Information
The Si516 supports a variety of options including frequency, minimum absolute pull range (APR), tuning slope,
output format, and V_DD. Specific device configurations are programmed into the Si516 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 and for further ordering instructions. The Si516 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: 516AAB000213AAG.
The series prefix, 516, indicates the device is a dual frequency VCXO.
The 1st option code A specifies the output format is LVPECL and powered from a 3.3 V supply. The Absolute Pull
Range code A indicates a temperature stability of ±20 ppm with a tuning slope of ±150 ppm/V. The 3rd option code
B specifies the frequencies are listed in descending order and FS = 0 selects the higher frequency.
The frequency code is 000213. Per this convention, and as indicated by the part number lookup utility at
www.silabs.com/VCXOpartnumber, the two output frequencies are 156.25 MHz and 125 MHz. The package code
A refers to the 5 x 7 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.
