**SiT1630 Ultra-Low Power, Ultra-Small 32.768 kHz Oscillator** 

 The Smart Timing Choice  The Smart Timing Choice 

## **Description** 

The SiT1630 is an ultra-small and ultra-low power 32.768 kHz oscillator optimized for battery-powered applications. 

SiTime’s MEMS oscillators consist of MEMS resonators and a programmable analog circuit. Our MEMS resonators are built with SiTime’s unique MEMS First™ process. A key manufacturing step is EpiSeal™ during which the MEMS resonator is annealed with temperatures over 1000°C. EpiSeal creates an extremely strong, clean, vacuum chamber that encapsulates the MEMS resonator and ensures the best performance and reliability. During EpiSeal, a poly silicon cap is grown on top of the resonator cavity, which eliminates the need for additional cap wafers or other exotic packaging. As a result, SiTime’s MEMS resonator die can be used like any other semiconductor die. One unique result of SiTime’s MEMS First and EpiSeal manufacturing processes is the capability to integrate SiTime’s MEMS die with a SOC, ASIC, microprocessor or analog die within a package to eliminate external timing components and provide a highly integrated, smaller, cheaper solution to the customer. 

## **Frequency Stability** 

The SiT1630 is factory calibrated (trimmed) to guarantee frequency stability to be less than 20 ppm at room temperature and very tight stability over temperature. Unlike quartz crystals that have a classic tuning fork parabola temperature curve with a 25°C turnover point, the SiT1630 temperature coefficient is extremely flat across temperature. 

When measuring the SiT1630 output frequency with a frequency counter, it is important to make sure the counter's gate time is >100 ms. The slow frequency of a 32 kHz clock will give false readings with faster gate times.

## **Power Supply Noise Immunity** 

The SiT1630 is an ultra-small 32 kHz oscillator. In addition to eliminating external output load capacitors common with standard XTALs, this device includes special power supply filtering and thus, eliminates the need for an external Vdd bypass-decoupling capacitor. This feature further simplifies the design and keeps the footprint as small as possible. Internal power supply filtering is designed to reject AC-noise greater than ±150 mVpp magnitude and beyond 10 MHz frequency component. 

## **Power-up** 

The SiT1630 starts-up to a valid output frequency within 300 ms (180 ms typ). To ensure the device starts-up within the specified limit, make sure the power-supply ramps-up in approximately 10 - 20 ms (to within 90% of Vdd).

## **Manufacturing Guidelines** 

- 1) No Ultrasonic Cleaning: Do not subject the SiT1630 to an ultrasonic cleaning environment. Permanent damage or long term reliability issues to the MEMS structure may occur. 

- 2) For Noisy, high EM environments, we recommend the following design guidelines: 

   - Place oscillator as far away from EM noise sources as possible (e.g., high-voltage switching regulators, motor drive control). 

   - Route noisy PCB traces, such as digital data lines or high di/dt power supply lines, away from the SiTime oscillator. 

   - Add a low ESR/ESL, 0.1uF to 1.0uF ceramic capacitor (X7R) to help filter high frequency noise on the Vdd power-supply line. Place it as close to the SiTime oscillator Vdd pin as possible. 

   - Place a solid GND plane underneath the SiTime oscillator to shield the oscillator from noisy traces on the other board layers.
