  SM843256
  10 Gigabit Ethernet and SONET, 6 output,
  Ultra-Low Jitter LVPECL Frequency
  Synthesizer General Description Features The SM843256 provides a low-noise timing solution for
  high speed, high accuracy synthesis of clock signals.
  Common applications include SONET, Gigabit Ethernet,
  10 Gigabit Ethernet, and similar networking standards. It
  includes a unique power reduction methodology, along
  with a patented RotaryWaveTM architecture that provides a
  very stable clock with very low noise.
  Power supplies of either 3.3V or 2.5V are supported, with
  superior jitter and phase noise performance. The device
  synthesizes different low noise LVPECL output
  frequencies such as 125MHz, 156.25MHz, 312.5MHz, and
  625MHz for Ethernet applications; 77.76MHz, 155.52MHz,
  311.04MHz, and 622.08MHz for SONET applications. The
  crystal reference frequencies used include 25MHz and
  19.44Mhz for Ethernet and SONET applications,
  respectively.
  The SM843256 is an excellent replacement for IDT Femtoclocks, with improved accuracy, power consumption,
  waveform integrity, and jitter.
