Differential oscillators are timing industry’s highest performing
SiTime Corporation has introduced a new series of differential oscillators with 10PPM stability and 500femtoseconds of jitter.
Touted as the highest performing oscillators in the timing industry, the SiT9121 and SiT9122 MEMS devices are targeted at high performance telecom, storage and networking applications, such as core and edge routers, cloud storage servers, wireless base stations and 10Gb Ethernet switches.
"Traditional differential oscillators that are based on legacy quartz, SAW and overtone technology have inherent limitations in stability and reliability," said Piyush Sevalia, vp of marketing at SiTime. "The new SiT912x differential oscillators offer a unique combination of ultra performance and programmable features that were developed with SiTime's analogue cmos and all silicon MEMS technology."
The devices have an operating voltage of between 2.5 and 3.3V and are available in industry standard footprints. Frequency ranges for the SiT9121 and SiT9122 are rated at 1 to 220Mhz and 220 to 650MHz, respectively.
