The Answer to 100G/400G Coherent Optics Timing Requirements

Today we announced our Si534xH clock family, a high-frequency, flexible clocking solution designed to cut cost and complexity for system-level development. The Si5344H and Si5342H clocks will replace current timing tools that rely on large, expensive voltage-controlled VCSOs that only support single, fixed frequencies. This frequency flexibility is coupled with jitter performance of 50 fs RMS.

The ability for service providers to send more data over existing fiber while minimizing the need for network upgrades is made possible by coherent optics, and this new offering simplifies things by integrating more functions into a smaller footprint.

 

Other features include:

  • Ultra-high-performance jitter-attenuating PLL designed for transmitter and receiver clocking
  • High-speed driver for data converter clocking of up to 2.7 GHz with ultra-low phase noise
  • Typical jitter performance of 50 fs RMS (1 MHz to 40 MHz)
  • MultiSynth fractional frequency synthesis for generating any frequency up to 712.5 MHz
  • Integrated loop filter with user-programmable PLL bandwidth for flexible jitter attenuation
  • High-speed, digitally tunable DCO mode: 0.001 ppb resolution with 1 MHz SPI update rate
  • Module-friendly size and power consumption
  • Simple, easy-to-use ClockBuilder Pro software

 

The Si5344H-EVB and Si5342H-EVB evaluation boards, priced at $199 each (USD MSRP), are available to simplify device evaluation and system-level timing design. To order clock samples and evaluation boards, visit www.silabs.com/timing.
