Sunnyvale, Calif.—SiTime Corp. has entered the voltage controlled oscillator (VCXO) market with what it says is the world's smallest programmable voltage controlled MEMS oscillator (VCMO) with the best pull-range linearity.

The SiT3701 comes with an array of programmable features such as frequency, voltage, tolerance and pull range, enabling delivery of customized samples in 24 hours and production quantities in 2 weeks.

According to SiTime, the SiT3701 features 0.5% pull range linearity, which is an order of magnitude better than quartz based VCXOs, and translates into simpler design, higher performance and improved stability and reliability. It comes in four standard package sizes with the smallest being 2.5 x 2.0 mm, making it well-suited for space-constrained applications.

The SiT3701 can be programmed for frequencies between 1 and 110 MHz; pull ranges of ±30 PPM, ±60 PPM, ±120 PPM or ±240 PPM; operating voltages of 1.8V, 2.5V, 2.8V or 3.3V; and frequency tolerance of ±25 PPM, ±30 PPM, ±50 PPM and ±100 PPM.

Pricing: $2.05 for 1K quantities in 7.0x5.0 packages.
Availability: Sampling; production quantities in the second quarter of 2009.
