3. Ordering Information
The Si512/513 supports a wide variety of options including frequency, stability, output format, and V_DD. Specific
device configurations are programmed into the Si512/513 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 and for
further ordering instructions. The Si512/513 XO 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.

Description
xxxxxx
This 6-digit code represents a unique
combination of two frequencies. Frequencies
from 100 kHz to 250 MHz (differential) or 212.5
MHz (CMOS) are supported. For more info:

Figure 2. Part Number Convention
Example part number: 512PCA000104BAGR:
The series prefix, 512, indicates the device is a Dual CMOS XO with the OE function on pin 2. The output format
code P specifies the outputs are dual in-phase CMOS with a 2.5 V supply. The frequency stability code C indicates
a total stability of ± 30 ppm. The frequency select and output enable code A specifies that the two frequencies are
listed in ascending order, with the output frequency f0 (the lower frequency) selected when FS=0, and f1 (the
higher frequency) selected when FS = 1. The device’s output enable polarity is active High.
The six-digit code is 000104. As specified by the part number lookup utility at www.silabs.com/VCXOpartnumber,
f0 is 155.52 MHz (the lower frequency) and f1 is 156.25 MHz (the higher frequency). The package code B refers to
the 3.2 x 5 mm footprint with six pins. The last A refers to the product revision, G indicates the temperature range
(–40 to +85^oC), and R means the device ships in tape and reel format.
Note: CMOS and Dual CMOS maximum frequency is 212.5 MHz.
