Silicon Laboratories - Si500 Low Jitter Silicon Oscillators

	Si500 Low Jitter Silicon Oscillators

Silicon Labs and Digi-Key introduce the Si500 series of single LC-based oscillators

Silicon Lab's Si500 silicon oscillators are some of the industry’s first high-performance programmable oscillators (XOs) available with 24-hour lead times. Silicon Labs’ 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 capable of generating any output frequency from 0.9 to 200 MHz. The Si500 is one of the first programmable silicon oscillators 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.

Overview

Unmatched Performance
Based on low phase noise silicon oscillator architecture and compensation circuitry, the Si500 provides a new level of performance and flexibility. The device is factory-programmable during production test to generate any frequency from 0.9 to 200 MHz. Each device is individually calibrated to meet +/-150 ppm total stability, inclusive of 25°C initial frequency accuracy, operating temperature range, supply voltage change, output load change, 1st year aging at 25°C, shock and vibration. Utilizing Silicon Labs’ ultra low jitter clock technology, the Si500 delivers jitter performance of 0.8 ps RMS period jitter that rivals the best quartz based oscillators and is significantly better than MEMs-based solutions.

Highest Reliability
The Si500 provides superior reliability than quartz oscillators. Quartz oscillators use a mechanical resonator that vibrates at the desired frequency, making the device susceptible to shock and vibration. Since the Si500 has no moving parts, it is not susceptible to shock and vibration effects. In addition, the Si500 provides superior reliability at start up and during long-term operation.
