CY2XP311 - 312.5 MHz LVPECL Clock Generator

Description

The CY2XP311 is a PLL (phase locked loop) based high performance clock generator.

It is optimized to generate 10 GB Ethernet, SONET, and other high performance clock frequencies.

It also produces an output frequency that is 12.5 times the crystal frequency.

Features

  • One LVPECL output pair.
  • Output frequency: 312.5 MHz.
  • External crystal frequency: 25 MHz.
  • Low RMS phase jitter at 312.5 MHz, using 25-MHz crystal (1.875 MHz to 20 MHz): 0.3 ps (typical).
  • Pb-free 8-pin TSSOP package.
  • Supply voltage: 3.3 V or 2.5 V.
  • Commercial and industrial temperature ranges Functional.
