SiTime is laying claim to the industry’s first EMI-reducing differential oscillators for PCI- Express and FB-DIMM applications in PCs, servers, RAID controllers, host bus adapters, networked attached storage (NAS), multi-service access platforms and high-end graphics dards. The micro-electro-mechanical system (MEMS) oscillator--the SiT9002AI--provides clocks for PCI-Express or FB-DIMM using built-in spread spectrum technology which reduces electro-magnetic interference (EMI) by up to 16 db with a frequency stability of ±50 PPM.
