Oscillation Circuit Evaluation Methods

NDK's Circuit Analysis Service for Stable Oscillation

It is necessary for a crystal unit to optimize the oscillation conditions under the matching between the oscillation circuit and the crystal unit as the crystal unit is a passive component. In the NDK circuit analysis, we confirm characteristics of a crystal unit on the customer's circuit board, perform the matching with the crystal unit, and propose appropriate conditions.
