9201-image

The SiT2025 is the industry's first AEC-Q100 compliant, high frequency clock generator with on-chip MEMS resonator, therefore eliminating any need for external crystals and other clock sources.  This device delivers the perfect of high frequency range (up to 137 MHz), excellent stability (±50 PPM) and extreme temperature range (-55 to 125°C).  It also features the industry's best 01 ppb/g vibration sensitivity, 50kg shock and 70g vibration resistance.

The SiT2025 comes in the small SOT23-5 package that offers best board level solder joint reliability.

Notes:
The voltage portion of the SiT2025 part number consists of two characters that denote the specific supply voltage of the device. The SiT2025 supports either 1.8V ±10% or any voltage between 2.25V and 3.62V. In the 1.8V mode, one can simply insert 18 in the part number. In the 2.5V to 3.3V mode, two digits such as 18, 25 or 33 can be used in the part number to reflect the desired voltage. Alternatively, “XX” can be used to indicate the entire operating voltage range from 2.25V to 3.63V.
