Timing Devices are devices that are made to record, store and /or exhibit time as and when required. Since ages, there have been many attempts made to design new type of timing devices. Starting from simple clock to time circuit, todays electronics has made it a wonder to keep time in the fashion we would like to do. Different alarms, timers, stopwatches belong to this category.
Timing Devices discusses about the companies manufacturing timing devices. IDT is a leading provider of timing solutions for communication, storage, industrial and digital consumer applications. The IDT portfolio of silicon timing devices offers differentiated solution elements, such as programmable platform, precision technology, advanced I/O and stratum-compliant synchronization. Specific families include devices for clock generation, programmable skew, zero delay and non-PLL based clock fanout.
Timing Devices focuses to Satellite Laser Ranging. In Satellite Laser Ranging (SLR), there are two types of timing measurements, the time (epoch) of laser fire and the roundtrip Time Of Flight (TOF) of the optical pulse. The minimum timing related hardware required for these measurements is a master clock/oscillator, a GPS receiver, and a TOF unit. Timing Devices points out to a few of the terminologies associated with timing devices.
Accuracy - the deviation of a measurement from a standard. Precision - the deviation of a set of measurements about their mean. Resolution - the minimum differential measurement which can be made. Stability - a measure of the constancy of some quantity over time. Jitter - the random displacement of a signal from its absolute location. Linearity - the relative accuracy between measurements. Allan Deviation - non-classical statistic used to estimate stability.
Crystals are naturally occurring materials that can be induced to resonate (vibrate) at an exact frequency. Quartz, a piezoelectric crystal that provides excellent mechanical and electrical stability, acquires a charge when compressed, twisted, or distorted. Delay lines are devices used to slow down a signal by a time interval in an electrical network. There are two basic delay line technologies: passive and active.
