3. Ordering Information
The Si554 supports a variety of options including frequency, temperature stability, tuning slope, output format, and
V DD . Specific device configurations are programmed into the Si554 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 Si554 VCXO series is supplied in an industry-standard, RoHS-compliant,
lead-free, 8-pad, 5 x 7 mm package. Tape and reel packaging is an ordering option.

6-digit Frequency Designator Code
Four 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 XOs programmed with
the lowest frequency value selected when FS[1:0] = 00, and the highest value when
FS[1:0] = 11. Six digit codes < 000100 refer to XOs programmed with the highest
frequency value selected when FS[1:0] = 00, and the lowest value when FS[1:0] = 11.

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.
Note :
CMOS available to 160 MHz.
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 over all
operating conditions.
3. Nominal Pull range (±) = 0.5 x V DD x tuning slope.
4. Nominal Absolute Pull Range ( ± APR) = Pull range – stability – lifetime aging
= 0.5 x V DD x tuning slope – stability – 10 ppm
5. Minimum APR values noted above include worst case values for all parameters.
6. Combination not available.
Example Part Number: 554AF000124DGR is a 5 x 7 mm Quad VCXO in an 8 pad package. Since the six digit code (000124) is > 000100, f0 is
622.08 MHz (lowest frequency), f1 is 644.53125, f2 is 657.42188, and f3 is 669.32658 MHz (highest frequency), with a 3.3 V supply, LVPECL
output, and Output Enable active high polarity. 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.
