SiT8008 Low-Power Expanded Voltage Range MEMS Oscillators

The popular SiT8008 low-power MEMS oscillators from SiTime Corporation can operate at any voltage between 1.62 V and 3.63 V. With this feature and the additional programmable features such as frequency and drive strength programmability, the SiT8008 offers millions of possible configurations. Industrial and medical applications such as factory automation, seismic sensing, and data acquisition all use many clock sources in a single system and can benefit tremendously from the programmable features of the SiT8008. SiTime has worked with DigiKey to ensure that the SiT8008 is available with short lead times.

Traditional oscillators are usually configured for specific frequencies and operation at one of 1.8 V, 2.5 V, or 3.3 V voltages. Each configuration then requires a separate component qualification and will need to be stocked in inventory. Simplicity is the name of the game with the SiT8008. Even if a customer uses multiple oscillator configurations, only one component qualification is required, thereby reducing the time burden on valuable engineering resources. The SiT8008’s ability to operate at any voltage between 1.62 V and 3.63 V further simplifies system design. A customer can choose the voltage rail that is already available in the system rather than designing a new one, which can also reduce component count. Along with continuous voltage operation, the SiT8008 also offers industry-leading resilience and reliability, a wide programmable frequency range with six decimals of accuracy, low power consumption, small package size, and short lead times.
