SiT3541 Datasheet

The SiT3541 is a ruggedized, ultra-low jitter, user-programmable oscillator with a maximum acceleration sensitivity of 0.1 ppb/g. SiT3541, designed for high-reliability applications, and conforms to MIL-PRF-55310 and MIL-STD-83 specifications to deliver functionality in the most demanding environments. The device supports two in-system programming options after powering up at a default, factory-programmed startup frequency: Any-frequency mode where the clock output can be re-programmed to any frequency between 1 MHz and 340 MHz in 1 Hz steps, and Digitally controlled oscillator (DCO) mode where the clock output can be steered or pulled by up to ±3200 ppm with 5 to 94 ppt resolution. The device’s default start-up frequency is specified in the ordering code. User programming of the device is achieved via I2C or SPI. Up to 16 I2C addresses can be specified by the user either as a factory programmable option or via hardware pins, enabling the device to share the I2C with other I2C devices.
