3. Ordering Information
The Si550 supports a variety of options including frequency, temperature stability, tuning slope, output format, and
V
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
and for further ordering instructions. The Si550 VCXO series is supplied in an industry-standard, RoHS compliant,
lead-free, 6-pad, 5 x 7 mm package. Tape and reel packaging is an ordering option.

the application’s minimum APR requirements. Unlike SAW-based solutions which
require higher higher Kv values to account for their higher temperature dependence,
the Si55x series provides lower Kv options to minimize noise coupling and jitter in real-
world PLL designs. See AN255 and AN266 for more information.
APR of ±25 ppm is able to lock to a clock with a ±25 ppm stability over 15 years over all
operating conditions.

Available frequency range is 10 to 945 MHz, 970 to 1134, and 1213 to
1417 MHz. The position of “M” shifts to denote higher or lower
frequencies. If the frequency of interest requires greater than 6 digit
resolution, a six digit code will be assigned for the specific frequency.
