3. Ordering Information
The Si552 was designed to support a variety of options including frequency, temperature stability, tuning slope,
output format, and VDD.
Specific device configurations are programmed into the Si552 at time of shipment.
Configurations are specified using the Part Number Configuration chart shown below. Silicon Labs provides a web

Refer
to
www.silabs.com/VCXOPartNumber to access this tool and for further ordering instructions. The Si552 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.
Figure 1. Part Number Convention
Example Part Number: 552AF000108BGR is a 5 x 7 mm Dual VCXO in a 6 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 and LVPECL output.
Temperature stability is specified as ±50 ppm and the tuning slope is 135 ppm/V. The part is specified for a –40 to +85 C° ambient
temperature range operation and is shipped in tape and reel format.

Notes:
1. For best jitter and phase noise performance, always choose the smallest Kv that meets
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.
2. APR is the ability of a VCXO to track a signal over the product lifetime. A VCXO with an
APR of ±25 ppm is able to lock to a clock with a ±25 ppm stability, over 15 years.
3. Nominal Pull range (±) = 0.5 x VDD x tuning slope.
4. Nominal Absolute Pull Range (±APR) = Pull range – stability – lifetime aging
=0.5 x VDD x tuning slope – stability – 10 ppm
5. Minimum APR values noted above include worst case values for all parameters.
6. Combination not available.

6-digit Frequency Designator Code
Two 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 dual XOs programmed
with the lower frequency value selected when FS = 0, and the higher value when FS = 1.
Six digit codes < 000100 refer to dual XOs programmed with the higher frequency value
selected when FS = 0, and the lower value when FS = 1.
