9201-image

The SiT2002B is the industry's first high frequency, one-output clock generator with embedded MEMS resonator.  This device features uncompromising combination of low power consumption, excellent stability, flexible supply voltage and the shortest lead time for high frequency applicaitons.  It comes in a small, 5-pin SOT23-5 package that offers the best board level solder joint reliability and enables low cost, optical-ONLY board level inspection.

For the same device in SMD packages, refer to the SiT8009B oscillator.
