Silicon Labs outs industry's lowest industrial jitter clocks

Silicon Labs has announced what it boasts as the industry's most frequency-flexible clock solutions providing industry-leading jitter performance for high-speed networking, communications and data centre equipment serving as the foundation of today's Internet infrastructure. The company's next-generation Si534x "clock-tree-on-a-chip" portfolio includes high-performance clock generators and highly integrated multi-PLL jitter attenuators.

These single-chip, ultra-low-jitter timing devices combine clock synthesis and jitter attenuation functionality to reduce the cost and complexity of optical networking, wireless infrastructure, broadband access/aggregation, Carrier Ethernet, test and measurement, and enterprise/data centre equipment including edge routers, switches, storage and servers.

Silicon Labs' Si534x jitter attenuators and clock generators leverage industry-leading frequency flexibility and clock-tree-on-a-chip integration to deliver an efficient, cost-effective solution that combines all discrete timing functions into a single-chip clock IC solution, noted the company.

The Si5347/46/45/44/42 jitter attenuators and Si5341/40 clock generators provide an I2C-configurable platform with an industry-leading combination of frequency translation capabilities and best-in-class jitter performance (<100fs RMS). By combining up to four independent jitter-attenuating PLLs and up to five ultra-low-jitter MultiSynth fractional synthesisers, the Si534x family is capable of generating up to 10 outputs with any combination of frequencies from 100Hz to 800MHz in a range of user-selectable output formats (LVPECL, LVDS, CML, HCSL and LVCMOS). This exceptional level of integration and frequency flexibility eliminates the need for multiple clock ICs, discrete level translation, loop filters and power supply filter components and significantly reduces BOM cost and complexity while still providing more than 50 per cent margin to stringent 10/40/100G jitter specifications.

With Silicon Labs' Si534x family and ClockBuilder Pro software, high-performance clock configuration has never been simpler or faster. ClockBuilder Pro is designed to help system designers quickly and easily create custom Si534x clocks for their applications. This easy-to-use software integrates the equivalent of more than 150 engineer-years of Silicon Labs' DSPLL timing technology and applications expertise to simplify clock tree design and speed time to market. Using the intuitive ClockBuilder Pro GUI, designers can quickly generate sophisticated device configurations in less than five minutes, minimising software development overhead.

Silicon Labs' complimentary ClockBuilder Go app for mobile devices simplifies the design process even further. System designers can quickly jumpstart their clock tree designs on their smartphones and tablets by leveraging Silicon Labs' built-in frequency planning algorithms to synthesize virtually any clock frequency. ClockBuilder Go is available for iOS mobile devices, and Android support will be available later this year.

Rather than waiting months to receive their custom clock orders, system designers simply upload their custom configurations to Silicon Labs through ClockBuilder Pro software. Factory pre-programmed Si534x clock samples ship in two weeks, accelerating the overall product development process with the industry's shortest custom sample lead times.

Factory pre-programmed samples of the Si534x clock generators and jitter attenuators are available in QFN packages as small as 7 x 7mm. Si5341/40 clock generator pricing in 10K quantities ranges from $4.75 to $10.60, and Si534x jitter attenuator 10K pricing ranges from $6 to $29. Silicon Labs' Si534x family evaluation boards, priced at $200 and $250, enable developers to move quickly from device configuration to detailed performance analysis to custom part number generation in less than five minutes. ClockBuilder Pro software is available from Silicon Labs' website at no charge.
