Real Stuff: Differential Crystal Oscillator in High-speed Transmission Network
What's differential crystal oscillators?

Differential crystal oscillators are oscillators that can output differential signals. Differential signals use the numerical difference between two physical quantities to represent a signal. Specifically, differential crystal oscillators send two signals of equal magnitude and opposite direction, and the receiving end determines whether the logical bit is 0 or 1 by comparing the difference between the two signals. This differential signal approach can eliminate common-mode noise and produce a higher-performance system. Differential crystal oscillators are widely used in clock oscillating circuits in computers, communication devices, and other electronic devices, clock recovery and data synchronization circuits in data communication, frequency synthesizers and local oscillators in wireless communication systems, clocks, counters, frequency meters, etc. in test and measurement equipment, clocks and synchronization circuits in audio equipment, data acquisition and control systems in industrial automation systems, and clock and data acquisition circuits in medical equipment.
