SIT2024B MEMS Oscillators

SiTime's automotive grade oscillators for extreme-temperature applications

SiTime Corporation's SiT2024B series are reliable and high quality AEC-Q100 compliant SOT-23 oscillators for automotive and extreme temperature applications. These devices deliver a combination of wide frequency range (1 MHz to 110 MHz), excellent stability (±20 ppm), and extreme temperature range (-55°C to +125°C). They also feature 0.1 ppb/g vibration sensitivity, 50,000 g shock, and 70 g vibration resistance. The small SOT23-5 package offers board-level solder joint reliability and easy, low-cost optical-only, board-level inspection of solder joints.

The SiT2024 includes a programmable drive strength feature to provide a simple, flexible tool to optimize the clock rise/fall time for specific applications. Benefits from the programmable drive strength feature include improved system radiated electromagnetic interference (EMI) by slowing down the clock rise/fall time, improved downstream clock receiver’s (RX) jitter by decreasing (speeding up) the clock rise/fall time, and the ability to drive large capacitive loads while maintaining full swing with sharp edge rates. The high-performance features of the SIT2024 series products make them suitable for automotive infotainment systems, collision detection system, powertrain, and in-vehicle networking applications.
