Product Description

PI6C4911504D2 is a high performance differential buffer with divide by 2 capability. There are also 2 selectable muxed inputs. This device is ideal for systems that need to distribute low jitter clock signals to multiple destinations with a change from the input frequency.


  • 2 pairs of selectable differential inputs
  • 2 divide by 2 differential LVPECL outputs and 2 buffered outputs
  • Maximum operating frequency: 650MHz
  • RMS additive jitter @ 156.25MHz (12kHz – 20MHz): 30fs (typical)
  • Output skew: 60ps
  • Part to part skew: 200ps
  • Operating voltage of 2.5V and 3.3V
  • Industrial operating temperature
  • Available in lead-free package


  • Networking: 10GbE, 25GbE, 40GbE and 100GbE applications
  • Telecom: Basestations and Access Points
