Highly stable CMOS oscillator

18 February 2009 Electronics Technology

Silicon Laboratories has announced its entry into the consumer timing market with the introduction of a high-stability CMOS oscillator, offering a replacement for crystal oscillators (XOs) with short lead times, low cost, high reliability and high performance.

The Si500 completely eliminates the quartz resonator that must be cut and tuned for each frequency, replacing it with an ultra-low phase noise silicon oscillator manufactured using standard, high-volume IC manufacturing processes capable of generating any output frequency from 0,9 to 200 MHz. The product family supports frequency stability options ranging from ±100 to ±150 ppm.

Because the oscillator relies on standard CMOS manufacturing and low-cost packaging, it is immune to the contamination issues that affect traditional hermetically-sealed ceramic or metal-packaged XOs during device assembly, providing high reliability at startup and guaranteed oscillation over the lifetime of the product. By eliminating the mechanical resonator used for frequency generation, it also provides high immunity to the shock and vibration that plagues traditional crystal oscillators.

The Si500 is claimed to be the first silicon oscillator in the industry to support differential clock outputs (LVPECL, LVDS, HCSL) in addition to CMOS and SSTL formats. It also supports a dual-output CMOS format mode in which a single device can produce two output clocks at the same frequency, eliminating the need for external clock buffers.
