Preliminary SC3015B 550.0 MHz Differential Sine-Wave Clock Quartz SAW Frequency Stability Fundamental Fixed Frequency Very Low Jitter and Power Consumption Rugged, Miniature, Surface-Mount Case Low-Voltage Power Supply (3.3 VDC) This digital clock is designed for use with high-speed CPUs and digitizers. 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.
