AUSTIN, Texas -- Silicon Laboratories Inc. (Nasdaq: SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today announced its entry into the frequency control market with the Si530 and Si550 families of oscillators (XOs) and voltage-controlled oscillators (VCXOs) for applications up to 1.4 GHz. These product families include the industry’s first quad frequency XO and VCXO devices. Leveraging the company’s proven DSPLL® technology, both the Si550 and Si530 families provide the industry’s shortest lead times, highest reliability and best performance, making them ideal for applications such as networking equipment, base stations, test and measurement equipment, storage area networks and video systems.

Silicon Laboratories invented the patented DSPLL approach to simplify the clock multiplication and jitter attenuation circuitry required in high-speed telecommunication applications. This technology is now the standard for replacing multiple discrete phase-locked-loop (PLL) components with a single IC that integrates digital signal processing (DSP) circuitry and an ultra low jitter voltage-controlled oscillator.

With optimized DSPLL technology, Silicon Laboratories is able to move frequency control and tuning from a complex resonator to a single CMOS IC, enabling the Si530 and Si550 families to deliver total frequency stability over time and temperature that is more than two times better than traditional high-frequency, low-jitter oscillators. DSPLL-based frequency tuning also enables up to a tenfold improvement in initial frequency accuracy when compared to designs based on traditional high-frequency SAW or crystal resonators.

"Silicon Laboratories' market-leading jitter performance challenged our best jitter measurement test system," said Amir Aghdaei, vice president of Agilent's Worldwide System Solutions Division. "We developed the JS-500 with very low intrinsic noise, great clock rate flexibility and true continuous peak-to-peak measurements specifically to help Silicon Laboratories verify their DSPLL-based products’ unmatched jitter performance metrics."
