SiTime Unveils MEMS VCTCXO for Telecom

SiTime Corporation unveiled a line of ultra-stable MEMS VCTCXO (Voltage Controlled, Temperature Compensated Oscillator) products targeted at telecom, networking and wireless applications like SONET and Synchronous Ethernet based equipment, cellular basestations and repeaters, GPS and instrumentation.


The devices are drop-in replacements for quartz-based oscillators but offer the durability and programmability of silicon MEMS technology. The new, programmable, Encore-based VCTCXO family consists of four devices, SiT5001, SiT5002, SiT5003 and SiT5004, all of which support frequencies up to 220 MHz, industry-leading stability as low as ±0.5 PPM and 500 femtoseconds of integrated RMS phase jitter (12 kHz to 20 MHz).


"SiTime has used its Silicon MEMS technology and programmable analog expertise to accelerate innovation in the timing components industry," said Piyush Sevalia, vice president of marketing at SiTime. "Unlike the quartz industry, SiTime offers web-enabled software development tools that allow engineers to customize a SiTime device exactly for their application, request samples, and receive them within a week. This flexibility, along with unique features, 3 – 5 week lead times and 10 times better reliability than quartz, is accelerating the electronics industry's move to MEMS-based timing."


Samples of the SiT500x devices are available now with production in late Q3, 2011. http://www.sitime.com
