Product Description

The PI6C4911504-03 is a high performance fanout buffer device which supports up to 1.5GHz frequency. PI6C4911504-03 features selectable single-ended clock or crystal inputs and translates to four LVPECL outputs. The outputs are synchronized with input clock during asynchronous assertion /deassertion of CLK_EN pin. PI6C4911504-03 is ideal for crystal or LVCMOS/ LVTTL to LVPECL translation. Typical clock translation and distribution applications are data-communications and telecommunications. This device is ideal for systems that need to distribute low jitter clock signals to multiple destinations.


  • 4 LVPECL outputs
  • Up to 1.5GHz output frequency
  • Ultra low additive phase jitter: < 0.03 ps (typ) (differential 156.25MHz, 12KHz to 20MHz integration range)
  • Two selectable inputs
  • Low delay from input to output (Tpd typ. 1.5ns)
  • 2.5V / 3.3V power supply
  • Industrial temperature support
  • TSSOP-20 package


  • Networking systems including switches and Routers
  • High frequency backplane based computing and telecom platforms
