SIT9347

The Endura™ SiT9347 ultra-low-jitter differential oscillator is engineered for harsh environments and is ideal for high-reliability aerospace and defense applications. This device supports any frequency from 220.000001 to 725 MHz in 1 Hz increments and delivers exceptional dynamic performance of 0.23 ps jitter (typ.) and ±10 ppm in the presence of common environmental stressors, such as shock, vibration, power supply noise, EMI, and board bending.

The SiT9347 is 100% screened through the SiTime Endura™ process flow to provide high reliability.

The device is available in s small 3.2 x 2.5 mm differential package in addition to a 7.0 x 5.0 mm package and supports all popular output signaling types including LVPECL, LVDS, and HCSL in combination with any voltage between 2.5 to 3.3V.
