1 to 220 MHz, Ultra-Low Jitter, ±15 to ±50 ppm VCXO
The Endura™ SiT3342 is a programmable differential VCXO (voltage controlled oscillator), engineered for harsh environments and ideal for high-reliability aerospace and defense applications. This device supports LVPECL, LVDS and HCSL output types with 27 exceptionally linear APR (absolute pull range) options up to ±3145 ppm. The SiT3342 delivers exceptional performance of 0.21 ps jitter (typ.), ±15 ppm, and 0.1% pull range linearity, and is designed to maintain these specs in the presence of common environmental stressors, such as shock, vibration, power supply noise, and EMI.
The MEMS-based Endura SiT3342 conforms to MIL-PRF-55310 and MIL-STD-883 specifications.
The SiT3342 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.
