The SiT3373 is a high-frequency, programmable differential VCXO (voltage controlled oscillator) that supports LVPECL, LVDS and HCSL output types with 27 exceptionally linear APR (absolute pull range) options up to ±3145 ppm. Based on SiTime's unique Elite Platform™, this device delivers exceptional dynamic performance of 0.23 ps jitter (typ.), ±15 ppm, and 0.1% pull range linearity with same excellent phase noise. Elite products are engineered to maintain these specs in the presence of common environmental hazards, such as shock, vibration, power supply noise, EMI, and board bending.
The SiT3373 can be factory-programmed to any combination of frequency, stability, voltage and pull range. This programmability enables designers to optimize clock configuration while eliminating the long lead time and customization costs associated with custom quartz VCXOs.
