An X-cut, 33.44 degree quartz crystal for propagating surface acoustic waves with a temperature stability in the order of -0.0209 ppm/C2. The crystal orientation requires only a single rotation (33.44 DEG ) from the crystal axes. This orientation is substantially simpler than previously reported cuts with comparable temperature stability which typically require three rotations. The X cut orientation has a surface acoustic wave (SAW) velocity of 3175 m/sec, an electromechanical coupling ( DELTA v/v) of 4x10-4, and a power flow angle of 2.7 degrees.
