SiTime unveils new digitally controlled oscillators to rival VCXOS

SiTime has introduced the SiT3907 MEMs based digitally controlled oscillator (DCXO) which is targeted at replacing quartz VCXOs in telecom and embedded applications.

Unlike analogue, quartz based VCXOs, the fully programmable SiT3907 DCXO features an in system digital control interface that is used for tuning the output frequency. The device is said to offer 100 times better linearity and eight times better pull range than quartz VCXOs to enable simpler, more reliable systems.

"SiTime's innovative MEMS technology and analogue expertise is leading the revolution in the timing industry," said Piyush Sevalia, executive vp of marketing at SiTime. "For decades, the quartz industry has offered VCXOs with no new features. Our customers requested an all digital control interface that simplified their design and improved performance."
