Digitally controlled MEMS-based oscillators offer superior linearity that is 1000 times better than traditional quartz VCXOs
New DCXO family from SiTime reduces the number of components required
Whereas conventional VCXOs require an external voltage to control the frequency, SiTime's DCXO family of products enable users to digitally control the output frequency. Therefore, a pull range from ±25 ppm to ±1600 ppm (parts per million) is achieved and the frequency resolution is 1 ppb (parts per billion).
The DCXOs provide superior pull range linearity of less than 0.01% which is 1000 times better than conventional quartz crystal VCXOs. Furthermore, unlike traditional VCXOs designs, external D/A converters are not required with the use of DCXOs, resulting in a reduction of the number of components needed for the circuitry.
SiTime's MEMS-based DCXOs provide developers with completely linear and low-noise solutions, which not only feature high accuracy and flexibility but also robustness and an unprecedented reliability.
The DCXOs come in three industry standard package sizes (3225, 5032 and 7050) and can optionally be operated with a supply voltage of 1.8 V, 2.5 V to 3.3 V. The first version, the SiT3907, is provided with LVCMOS outputs. Versions with differential outputs should come onto the market in the course of the next year.
