1 to 220 MHz Ultra-low Jitter Differential VCXO
LoginThe SiT3372 is a 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 0.21 ps jitter (typ.), ±15 ppm, and 0.1% pull range linearity with the 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, and EMI.
The SiT3372 can be 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.
