High stability MEMS-based XOs for automotive operating temperature range

January 28, 2013 // By Christoph Hammerschmidt
Components distributor MSC has introduced the SiT1618 MEMS XO family from SiTime. These oscillators, which are designed for the extended industrial operating temperature range from ‑40°C to +125°C, feature excellent frequency stability up to ±25 ppm inclusive of all conditions, G‑sensitivity of only 0.1 ppb and low power consumption of 3.6 mA.

These MEMS XOs are fully compatible with existing quartz-based XO solutions and are available with 33 standard frequencies between 7.3728 MHz and 48 MHz. The required supply voltage is optionally 1.8 V, 2.5 V, 2.8 V, 3.0 V or 3.3 V.

The SiT1618 family devices are available in industry standard 4-pin 2016, 2520, 3225, 5032 and 7050 packages, and are also suited for the extended industrial temperature range from -40°C to +105°C. These MEMS XOs are suitable for applications in the automotive, medical and industrial electronics sectors. AEC-Q100 compliance is available upon request.

The SiT1618 will be on display at the MSC booth #2-219 in Hall 2 at embedded world 2013, February 26‑28, 2013 in Nuremberg, Germany.
