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.
is typically A100pm at 25 degrees C.
at 25[degrees]C is [+ or -]10 ppm and their frequency stability vs.
the] first products already have achieved six-sigma process capability to provide [+ or -]50-ppm frequency tolerance
including initial offset and long-term drift over the full industrial temperature range from -40[degrees]C to + 85[degrees]C.
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.
The ceramic resonator can be manufactured to a frequency tolerance
of less than 0.
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.
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.
at 25[degrees]C is -20 to +20 ppm and frequency stability is -0.
Motors have a fairly tight frequency tolerance
requirement of plus or minus five percent.
