Silicon Labs’ Si538x and Si534x clock generators provide fast, free and easy customization for Any Frequency on Any Output with No Compromise on performance or specifications. 


Si538x Features

  • Digital frequency synthesis eliminates external VCXO and analog loop filter components
  • Supports JESD204B clocking: DCLK and SYSREF
  • Input frequency range: 10 MHz – 750 MHz
  • Output frequency range: 480 kHz – 1.47456 GHz
  • Excellent jitter performance: 80 fs typ (12 kHz – 20 MHz)

Si534x Features


  • Supported Devices: Si5340/1, Si5342/4/5, Si5346/7
  • Any frequency on any output: 1 kHz to 800 MHz
  • Any format on any output: LVPECL, CML, LVDS, HCSL, LVCMOS, HSTL, SSTL
  • Exact clock synthesis (0 ppm error)
  • As low as 100 fs rms phase jitter with the lowest fractional synthesis jitter in the industry
  • Accommodates any crystal or reference clock frequency




  • Networking, Communications, Storage, Servers, Audio/video, xDSL infrastructure, Cable infrastructure, Wireless infrastructure, Medical equipment, Test and measurement, Industrial
