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.

Figure 2. Part Number Convention

Example ordering part number: 516AAB000213AAG.

The series prefix, 516, indicates the device is a dual frequency VCXO.

The 1st option code A specifies the output format is LVPECL and powered from a 3.3 V supply. The Absolute Pull

Range code A indicates a temperature stability of ±20 ppm with a tuning slope of ±150 ppm/V. The 3rd option code

B specifies the frequencies are listed in descending order and FS = 0 selects the higher frequency.

The frequency code is 000213. Per this convention, and as indicated by the part number lookup utility at

A refers to the 5 x 7 mm footprint with six pins. The last A refers to the product revision, G indicates the

temperature range (–40 to +85 °C), and R specifies the device ships in tape and reel format.
