SiTime Introduces Industry's First EMI-Reducing Differential Oscillator

 

SiTime Corporation has unveiled the EMI-reducing differential oscillators for PCI-Express or FB-DIMM, which are said to be the first of its kind in the industry. This product can be used to provide clocks for PCI-Express or FB-DIMM to the high volume applications such as personal computers, servers, and RAID controllers.

 

Facilitating easy and cost-effective replacement of quartz-based solutions, the new devices are available in industry-standard footprints. While the production quantities are available in 2-3 weeks, customized samples are available in 24-hours. SiTime provides a wide variety of differential output programmable oscillators and clock generators that operate at frequencies from 1 to 800 MHz and can support LVPECL, LVDS, CML and HCSL signaling.

 

According to SiTime, the SiT9002AI oscillators provide various features that are compliant with PCI-Express and FB-DIMM timing standards. The differential outputs are configured to comply with the High-Speed Current Steering Logic (HCSL) specification. With the help of SiT9002AI's 0.5 percent down-spread spread spectrum technology, designers can reduce EMI up to 16 dB and pass compliance testing without excessive delays.

 

“SiTime's MEMS-based, high-performance, programmable timing solutions lead the industry in offering unique features that solve system problems and accelerate time to revenue," said Piyush Sevalia, vice president of marketing at SiTime. "The 100 MHz and 200 MHz SiT9002AI oscillators are flexible timing solutions for PCI-Express or FB-DIMM in networking, storage and computing applications.”

 

The SiT9002AI oscillators provides features such as Power supply voltage of 3.3V or 2.5V, Output frequency of 100 MHz or 200 MHz for PCI-Express or FB-DIMM and other customized frequencies, which are available upon request.

 

In November of last year, the company introduced a new family of programmable spread spectrum clock oscillators which are the smallest in the industry. They offer a wide frequency range of operation and also low cycle to cycle jitter. The other product introduced as part of the product line is the SiT9002 which is a differential output programmable spread spectrum clock oscillator.
