This digital clock is designed for use in high-speed communications timing systems. Fundamental-mode oscillation is made possible by surface-acoustic-wave (SAW) technology. The design results in low jitter, compact size, and low power consumption. Differential outputs provide a sine wave that is capable of driving 50 ? loads.
