Description
The SiT3800 is a high performance Voltage Controlled
MEMS Oscillator, VCMO (VCXO equivalent), suitable
for most communication applications. The pull range
can be set to +/-240ppm (480ppm total) or +/-60ppm
(120ppm total). The SiT3800 offers unparalleled
flexibility in terms of frequency range, frequency
accuracy tolerance, supply voltage, and operating
temperature range while simultaneously offering
outstanding performance in terms of linearity of the
VCMO pull range.
The SiT3800 is a factory programmable device that
enables user to pull the frequency by applying 0V to

1.6V to the VCMO control pin (pin1).
The SiT3800, by eliminating the external quartz
crystal, has improved immunity to the
environmental effects of vibration, shock, strain,
and humidity.
