6. Ordering Information
The Si514 supports a wide variety of options including startup frequency, stability, output format, and VDD. Specific
device configurations are programmed into the Si514 at time of shipment. Configurations can be specified using
the Part Number Configuration chart 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 Si514 XO series
is supplied in industry-standard, RoHS-compliant, 3.2 x 5.0 mm and 5 x 7 mm packages. Tape and reel packaging
is an ordering option.

Description
The Si514 supports a user-defined start-up
frequency which must be in the same range as
specified by the Frequency Grade code. A
user-defined, 7-bit I2C address is supported.
Each unique start-up frequency/I2C address
combination is assigned a 6-digit code by:
www.silabs.com/VCXOPartNumber.
Figure 8. Part Number Convention
Example orderable part number: 514ECB000107AAG supports 2.5 V LVPECL, ±30 ppm total stability, user
programmable output frequency range from 100 kHz to 170 MHz, 5x7 mm package and –40 to 85 °C temperature
range. The frequency code designates 10 MHz startup with I2C address of 0x55. Refer to www.silabs.com/VCXO
lookup to look up the attributes of any Silicon Labs orderable XO/VCXO part number.
Note: CMOS and Dual CMOS maximum frequency is 212.5 MHz.
