The SiT9002 is the world’s first programmable, differential output, spread spectrum oscillator.

The SiT9002 is optimized for high-performance networking and computing applications and supports LVDS, LVPECL, CML, and HCSL differential signaling standards, all of which are factory programmable. The device is available in six pad 5.0 x 3.2 mm and 7.0 x 5.0 mm standard-footprint packages.  Customers can replace existing oscillators in their design with the SiT9002, reduce their EMI and pass compliance tests without the need for an expensive board redesign, and without significant delays.

Additional programmable features on the SiT9002 include selection of any clock frequency between 1 MHz to 220 MHz; operating voltages of 1.8 V, 2.5 V or 3.3 V; frequency tolerance of ±25 PPM or ±50 PPM when spread is turned off; and down spread or center spread options for optimal EMI reduction. And, like the SiT9001, the device delivers cycle to cycle jitter of less than 30 ps, the lowest in the industry for a spread spectrum oscillator. Like all SiTime products, the SiT9002 differential output programmable spread spectrum oscillator is lead-free and RoHS compliant.
