Description
Commercial: 0º to 70ºC
TRISTATE, 50 MHz to 105 MHz
These oscillators are an important landmark in SMD oscillators due to the use
of inverted mesa crystals. These crystals
operate at fundamental frequency, providing a clean waveform with fast rise
and fall times and guaranteed low jitter
less than 5 ps RMS. These oscillators
are intended for telecom applications
which require very low jitter.
FEATURES
• Exceptionally clean waveform due to inverted mesa crystal
• Jitter is less than 5 ps rms
• Very fast rise time
• 5 x 7 mm Surface Mount Device
• Start up time less than 5 ms
• Stability choice of ±50 ppm or ±100 ppm
• Guaranteed start-up with ramping DC Supply
• 45/55 symmetry is standard
• Very low power when tristated
MF Electronics’ creation of a proprietary
multi-layer gold-ceramic package has
ushered in a new generation of tiny,
robust surface mount oscillators.
Measuring only 5 x 7 x 1.9 mm, the
T-Oscillators (T is for tiny) significantly
reduce PCB real estate, saving board
space, and permitting new value-adding
functions. They are intended for the most
stringent telecommunications applications where small size and excellent
waveform characteristics are required.
TYPCIAL APPLICATIONS
These oscillators are intended for high-speed data communications applications such as Gigabit Ethernet
and Fibre Channel. Common frequencies are: 53.125 MHz, 62.5 MHz, 75.0 MHz and 100.0 MHz.
