Overview

Product Description

The PI6CFGL401B is an 4-output very low power clock genera- tor for PCIe Gen1-2-3 applications with integrated output ter- minations providing Zo=100Ω. The device has 4 output enables for clock management and supports 2 different spread spectrum levels in addition to spread off. The device also has one 1.8V LVCMOS REF output. 

Features

  • 25MHz crystal or reference clock input
  • 100MHz low power HCSL or LVDS compatible outputs
  • PCIe 3.0, 2.0 and 1.0 compliant
  • Selectable spread spectrum of -0.25%, -0.5% and no spread
  • Programmable output amplitude and slew rate
  • Cycle-to-cycle jitter (typ.) ~ 30ps
  • Supply voltage of 3.3V+/-10%
  • Output supply voltage of 1.8V
  • Industrial ambient operating temperature
  • Available in lead-free package: 32-TQFN 

Applications

  • PCIe Gen1-2-3 clock generator
