The SiT9365 ultra-low-jitter differential oscillator supports 32 commonly used output frequencies for networking, storage, server, and FPGA clocking. Based on SiTime's unique Elite Platform™, this device delivers exceptional dynamic performance of 0.23 ps jitter (typ.) and stable timing in the presence of common environmental hazards, such as shock, vibration, power supply noise, and EMI.

The SiT9365 is available in the smallest 3.2 x 2.5 mm differential package in addition to the 7.0 x 5.0 mm package. This device supports all popular output signaling types including LVPECL, LVDS, and HCSL in combination with any voltage between 2.5 to 3.3 V.
