Figure 2. Part Number Convention
Example ordering part number: 515BBB212M500BAGR.
The series prefix, 515, indicates the device is a single frequency VCXO.
The 1st option code B specifies the output format is LVDS and powered from a 3.3 V supply. The stability and APR
code B indicates a temperature stability of ±20 ppm with a tuning slope of ±120 ppm/V. The 3rd option code B
specifies the OE pin is active low.
The frequency code is 212M500. Per this convention, and as indicated by the part number lookup utility at
www.skyworksinc.com/en/application-pages/timing-lookup-customize, the output frequency is 212.5 MHz. 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 °C), and R specifies the device ships in tape and reel format.
Note: CMOS and Dual CMOS maximum frequency is 212.5 MHz.

All dimensions shown are in millimeters (mm) unless otherwise noted.
Dimensioning and Tolerancing is per the ANSI Y14.5M-1994 specification.
This Land Pattern Design is based on the IPC-7351 guidelines.
All dimensions shown are at Maximum Material Condition (MMC). Least Material Condition
(LMC) is calculated based on a Fabrication Allowance of 0.05 mm.
Solder Mask Design
5. All metal pads are to be non-solder mask defined (NSMD). Clearance between the solder
mask and the metal pad is to be 60 µm minimum, all the way around the pad.
Stencil Design
6. A stainless steel, laser-cut and electro-polished stencil with trapezoidal walls should be used
to assure good solder paste release.
7. The stencil thickness should be 0.125 mm (5 mils).
8. The ratio of stencil aperture to land pad size should be 1:1.
Card Assembly
9. A No-Clean, Type-3 solder paste is recommended.
10. The recommended card reflow profile is per the JEDEC/IPC J-STD-020 specification for
Small Body Components.
