Description

The PI6LC48P03 is a 3-output LVPECL synthesizer optimized to generate Ethernet reference clock frequencies and is a member of Diodes' HiFlex family of high performance clock solutions. Using a 31.25MHz or 26.041666MHz crystal, the most popular Ethernet frequencies can be generated based on the settings of 4 frequency select pins.
The PI6LC48P03 uses Diodes' proprietary low phase noise PLL technology to achieve ultra low phase jitter, so it is ideal for Ethernet interface in all kind of systems.

Features

  • Three differential LVPECL output pairs
  • Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended clock input
  • Supports the following output frequencies: 125MHz, 156.25MHz, 312.5MHz, 625MHz
  • RMS phase jitter @ 156.25MHz, using a 31.25MHz or 26.041666MHz crystal (12kHz – 20MHz): 0.3ps (typical)
  • Full 3.3V or 2.5V supply modes
  • Commercial and industrial ambient operating temperature
  • Available in lead-free package: 24-TSSOP

Applications

  • Networking Systems
