Silicon Labs and Digi-Key Partner to Deliver the Only High-Performance Programmable Oscillators with 24-Hour Lead Times

July 19, 2010

AUSTIN, Texas & THIEF RIVER FALLS, Minn., Jul 19, 2010 (BUSINESS WIRE) -- Silicon Laboratories Inc. (NASDAQ: SLAB) and electronic components distributor Digi-Key Corporation today announced the industry's first high-performance programmable oscillators (XOs) available with 24-hour lead times. Silicon Labs' Si500 and Si590 low jitter oscillators support frequencies up to 525MHz with either single ended or differential output formats while eliminating the long lead times typical of traditional oscillators.

Silicon Labs' Si590/591 crystal oscillators provide low jitter clock generation and support any frequency from 10 to 525MHz, any format (CMOS, LVDS, LVPECL, CML), and any supply voltage (1.8, 2.5, or 3.3V), with guaranteed low jitter of 1 ps rms (max). The Si590/591 devices also offer +/-50ppm stability across all operating conditions, including the -40C to +85C industrial temperature range and with 15 years of aging. Digi-Key's on-site digital programming simplifies procurement of standard and custom frequencies, eliminating non-recurring expense (NRE) charges and minimum order quantities typically required for custom-frequency XOs. This results in lower development and initial production costs.

Silicon Labs' Si500 provides a low cost alternative to quartz based oscillators, by using an ultra-low phase noise all-silicon oscillator to generate any output frequency from 0.9 to 200MHz. The Si500 is the first programmable silicon oscillator in the industry to support differential clock outputs (LVPECL, LVDS, HCSL) in addition to CMOS format, providing customers added design flexibility and improved signal integrity. The devices can be programmed on-site by Digi-Key and therefore can be customized and shipped immediately while offering higher performance and reliability.

"Fast, efficient delivery of oscillators has been a wrench in the works of the supply chain for decades," said Mike Petrowski, general manager of timing products at Silicon Labs. "By partnering with Digi-Key to enable 24-hour lead times for high performance programmable devices, we are able to offer customers a path to better system optimization, lower cost and faster time to market."

"Because of Digi-Key's commitment to providing the best service possible and our strong partnership with Silicon Labs, our customers will experience the benefits of 24-hour lead times for the Si500 and Si590/591 products. Digi-Key can program and ship these oscillators within 24 hours of order receipt for delivery within 24-72 hours, depending on the delivery location," said Dave Doherty, Digi-Key's vice president of semiconductor product. "We are pleased to offer this industry-first to the thousands of design engineers who rely on Digi-Key to provide them with the latest and most innovative products for their designs."
