SiT2024B: AEC-Q100, One-output Clock Generator with -55°C to 125°C Temp Range

E-mail Print

The SiT2024B is the industry's first AEC-Q100 compliant, one-output clock generator with on-chip MEMS resontor, therefore eliminating  the need for external crstyals and other clock sources.  This device delivers the perfect combination of wide frequency range (1 MHz to 110 MHz), excellent stability (±20 PPM) and extreme temperature range (-55 to 125°C). It also features the industry's best 0.1 ppb/G vibration sensitivity, 50kg shock and 70g vibration resistance.

The SiT2024 comes in the small SOT23-5 package that offers the best board level solder joint reliability.

Note: 12. The voltage portion of the SiT2024 part number consists of two characters that denote the specific supply voltage of the device. The SiT2024 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.
