SiTime's programmable spread spectrum oscillators incorporate an industry-leading, highly reliable MEMS resonator and advanced analog circuits to provide EMI reduction of up to 12 dB with the lowest cycle-to-cycle jitter in the industry. Every programmable spread spectrum device, whether single-ended or differential, is available in industry standard footprints and packages. This feature allows easy replacement of conventional oscillators in systems without costly layout or design changes, ensuring that product delivery schedule is met and time to revenue is short.
Programmable features of SiTime’s spread-spectrum products include amount of down spreading or center spreading, frequency (as high as 800 MHz), operating voltage (1.8 V, 2.5 V, 2.8 V and 3.3 V), frequency tolerance when spread is off (±25 PPM, ±50 PPM and ±100 PPM) and output signaling types (LVPECL, LVDS, CML or HCSL). These programmable features enable unparalleled flexibility and fast customization with very short lead times (samples in 24 hours and production quantities in two weeks).
