Silicon Labs introduced the industry’s most frequency-flexible clock solutions offering industry-leading jitter performance for high-speed networking,
communications and data center equipment serving as the foundation of today’s Internet infrastructure. Silicon Labs’ 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 center equipment including edge routers, switches, storage and servers.
Silicon Labs’ 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 ( < 100 fs RMS). By combining up to four independent jitter-attenuating PLLs and up to five ultra-low-jitter MultiSynth fractional synthesizers, the Si534x family is capable of generating up to 10 outputs with any combination of frequencies from 100 Hz to 800 MHz in a wide 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 bill of materials (BOM) cost and complexity while still providing more than 50 percent margin to stringent 10/40/100G jitter specifications.
Simplifying Clock Trees with ClockBuilder Pro With Silicon Labs’ Si534x family and new 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, minimizing 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 today 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.
Pricing and Availability
Factory pre-programmed samples of the Si534x clock generators and jitter attenuators are available now in QFN packages as small as 7 mm x 7 mm. Si5341/40 clock generator pricing in 10K quantities ranges from $4.75 to $10.60 (USD), and Si534x jitter attenuator 10K pricing ranges from $6.00 to $29.00 (USD). Silicon Labs’ Si534x family evaluation boards, priced at $200 and $250 (USD MSRP), 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.
