Technological Advantages of Photolithographic Crystal BK for Automotive
We developed the crystal blank for use in crystal units intended for automotive applications, using high-quality crystal blanks and high-precision photolithography processing. We report 76.8 MHz crystal unit for automotive module applications that achieves a stable frequency stability of ±1.5 ppm at high drive level (DL), and 24MHz crystal unit using a mesa-type structure BK that achieves low equivalent series resistance (ESR).
