Description

The PI6LC48P03A 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 PI6LC48P03A 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
  • Industrial operating temperature
  • Available in lead-free package: 28-TQFN

Applications

  • Networking systems

FAQs

PI6LC48P0101 FAQs

What is LVPECL clock and its termination?

LVPECL is Low Voltage Positive (supply) Emitter Couple Logic. Its voltage level is around 2V+/-400mV and the most use termination is 150 ohm pull-down at output pin and AC or DC coupling to an equivalent 100 ohm across pair at RX ASIC side. Check ASIC datasheet  to prevent double termination.
