Figure 47. VCXO Crystal Pullability
VCXO Crystal Pullability has been gathered from following the evaluation environment.
Evaluation board: 70mm x 70mm x 1.6mm, 4 layers、FR-4
Using parts : 27MHz Crystal (DSX321G・8pF load) made in DAISHINKU CORP. RD=200Ω, CL=4pF
VCXO Crystal Pullability modulates by a using crystal and a board condition.
In order to use, should be checked matting with a final board condition.
