Description

The PI6LC48C51 is a single LVCMOS output synthesizer optimized to generate Ethernet, SONET/SDH, or SATA reference clock frequencies and is a member of Diodes' HiFlex family of high performance clock solutions. Using a MHz crystal with different frequencies, It can generate various output frequencies with very low phase jitter.
It is ideal for Ethernet, SONET/SDH, and SATA/SAS interfaces in all kind of systems.

Features

  • Single LVCMOS output
  • Supports 70MHz - 170MHz output frequency range
  • RMS phase jitter @ 155.52MHz, (1.875MHz – 20MHz): 0.2ps (typical)
  • Full 3.3V or 2.5V supply modes
  • Industrial ambient operating temperature
  • Available in lead-free package: 8-TSSOP

Applications

  • Networking systems
  • SONET / SDH systems
  • Server / Storage Systems

FAQs

PI6LC48C51 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.
