Spread Spectrum Modes
In both modes, triangle modulation is employed with a frequency of ~32 kHz.
The SiT9001 can be factory programmed to provide down spread modulation or center spread modulation. In the down spread
modulation mode, pin 1 can be factory programmed as a spread disable pin. In both the down spread and center spread
modulation modes, pin can be factory programmed to be either output enable or standby.
Description
The SiT9001 is a spread-spectrum capable, programmable
MEMS oscillator. The SiT9001 offers unparalleled flexibility in
terms of frequency range, frequency accuracy stability, supply
voltage, and operating temperature range while simultane-
ously offering outstanding performance in terms of low jitter
and a higher frequency range. This flexibility and high perfor-
mance is made available in packages down to 2.5 x 2.0 mm,
making
spread-spectrum oscillator available.
The SiT9001 is factory programmable and offers two types of
spread modulation: down spread modulation, and center

spread modulation. In down spread modulation mode, a
spread disable pin is available (Pin 1).
Power down (either output enable or standby) mode options
are available for both down spread and center spread versions
of the SiT9001.
The SiT9001, by eliminating the quartz crystal, has improved
immunity, shock, strain and humidity.
