The SiT9201 is the industry's first one-output clock generator with embedded MEMS resonator.  This device features the widest frequency range, the lowest power consumption, the best stability and the shortest lead time for consumer, networking, industrial and other applications. It comes in a 5-pin, small SOT23 package that offers the best board level solder joint reliability and enables low cost, optical-ONLY board level inspection.

For the same device in a SMD packages, refer to the SiT8008 oscillator.
