By default, ports are driven at the tile's reference clock.
2.
Non-coherent modulation methods do not require a receiver reference clock signal that is asynchronously transferred.
3.
A 5 MHz reference clock drives a phase-locked loop to produce a stable 500 MHz clock.
4.
Some PLLs also include a divider between the reference clock and the reference input to the phase detector.
5.
Long-baseline interferometry, which astronomers use to make highly accurate observations of distant objects, needs extremely accurate atomic reference clocks.
6.
Multiple techniques have been developed, often transferring reference clock synchronization from one point to another, often over long distances.
7.
The number represents the distance from the reference clock and is used to prevent cyclical dependencies in the hierarchy.
8.
For long time intervals, the error due to instabilities in the reference clock ( jitter ) plays a major role.
9.
Left alone, the wall clock will continue to diverge from the reference clock at the same few seconds per hour rate.
10.
This worked similar to the host clock, but could be used to provide any reference clock signal, independent of the host platform.
