Additionally, the trend toward smaller, more functional, better-performing electronic devices is also fueling demand for clock oscillators that offer tighter frequency tolerance over a wider operating temperature range.
It is interesting to note in Figure 18(b) the significant improvement in terms of sinusoidal frequency tolerance of the combined architectures in relation to the single stage CPR solely based on BPS.
Frequency tolerance at 25[degrees]C is [+ or -]10 ppm and their frequency stability vs.
To put the frequency tolerance in perspective, Michael Semos, a product marketing engineer at Epson Electronics America, Timing Products Business Unit, said, "The available frequency tolerances are based on market requirements, and the majority of applications we serve still requires from [+ or -]50 ppm to [+ or -]100 ppm."
* Frequency Tolerance of [+ or -] 4.60 ppm for 20 years.
Anti-aging resonators- Both MEMS resonators and quartz crystals have three primary frequency error terms that make up the total frequency tolerance measured in parts per million (ppm).
"This product is not as small as some ceramic oscillators, but it outperforms those ceramic oscillators in accuracy and stability, in frequency tolerance and frequency temperature characteristics at room temperature.
Equation 11 is a useful design equation requiring [[tau].sub.0] to be small to allow for a relaxed (large) frequency tolerance. This is in contradiction to the criterion for large [[tau].sub.0] desirable in discriminating between test and reference signals.
According to Agere the qualification was given after the W7020 met performance requirements in a series of tests designed to check the device`s frequency tolerance, power output, range and transmission.
Frequency tolerance is available down to [+ or -]10 ppm whilst frequency stability can be specified at -[+ or -]40 ppm over the full military temperature range of -55[degrees]C to 125[degrees]C down to -[+ or -]10 ppm over commercial temperature ranges coupled with low frequency aging characteristics.
The ceramic resonator can be manufactured to a frequency tolerance of less than 0.1 percent at 9.95 GHz.
