0 MHz Differential Sine-Wave Clock • • • • • Quartz SAW Frequency Stability Fundamental Fixed Frequency Excellent Jitter and Symmetry Rugged, Miniature, Surface-Mount Case Low-Voltage Power Supply (3.
3 VDC) This digital clock is designed for use in telecom applications; such as Timing for Terabit Router applications.
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 made to drive 50 Ω loads.
