The SiT9365 from SiTime is a Differential MEMS Crystal Oscillator that operates from 25 to 325 MHz. It provides LVPECL, LVDS, and HCSL outputs with a frequency stability of ±10 ppm. This oscillator is based on SiTime’s unique DualMEMS® temperature sensing and TurboCompensation® technology and is designed for low-jitter applications. It 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 oscillator also integrates multiple on-chip regulators to filter power supply noise, eliminating the need for a dedicated external LDO. It requires a DC supply from 2.5 to 3.3 V.
The SiT9365 can be factory programmed for specific combinations of frequency, stability, voltage, and output signaling. Programmability enables designers to optimize clock configurations while eliminating long lead times and customization costs associated with quartz devices where each frequency is custom built. This oscillator is available in packages with varying dimensions and is suitable for use in 10/40/100 Gbps ethernet, SONET, SATA, SAS, fiber channel, telecom, networking, instrumentation, storage and servers.
