Product Description

The PI6LC48P21 is a single output LVPECL synthesizer opti- mized to generate Ethernet reference clock frequencies and is a member of Diodes' HiFlex family of high performance clock solutions. Using a 25MHz or 26.6MHz crystal, it can generate 125MHz or 133MHz output frequencies.

The PI6LC48P21 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

  • Single differential LVPECL output
  • Supports the following output frequencies: 125MHz or 133MHz
  • RMS phase jitter @ 125MHz, using a 25MHz 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: 8-TSSOP 

Applications

  • Networking systems
