XOs and VCXOs fit applications up to 1.4 GHz

The Si530 and Si550 families of oscillators (XOs) and voltage-controlled oscillators (VCXOs) are aimed at applications up to 1.4 GHz. The families include what Silicon Labs is calling the industry's first quad frequency XO and VCXO devices.

Using the company's DSPLL technology, frequency control and tuning can be moved from a complex resonator to one CMOS IC, enabling the two families to deliver total frequency stability over time and temperature that's more than 2X better than traditional high-frequency, low-jitter oscillators. DSPLL-based frequency tuning also enables up to a 10X improvement in initial frequency accuracy when compared to designs based on traditional high-frequency SAW or crystal resonators.

Both XO and VCXO product families support operation over a frequency range from 10 MHz to 1.4 GHz with less than 0.3-ps RMS jitter. The Si530 and Si550 families also offer significantly improved control voltage linearity while providing a wide selection of voltage gain and pull range options.

The Si530 and Si550 devices are available in a standard, RoHS-compliant, 7-by 5-mm surface-mount package with support for all common output formats, including PECL, LVDS, CMOS, and CML. Depending on the feature set, prices range from $6.05 to $88.95 in quantities of 1000. For more information, visit www.silabs.com.
