Product Description

The PI6C557-03 is a spread spectrum clock generator supporting PCI Express and Ethernet requirements. The device is used for PC or embedded systems to substantially reduce Electromagnetic Interference (EMI).

The PI6C557-03 provides two differential (HCSL) spread spectrum outputs. The PI6C557-03 is configured to select spread and clock selection. Using Diodes' patented Phase-Locked Loop (PLL) techniques, the device takes a 25MHz crystal input and produces two pairs of differential outputs (HCSL) at 25MHz, 100MHz, 125MHz and 200MHz clock frequencies. It also provides spread selection of ±0.25%, -0.5%, -0.75%, and no spread.

Features

  • LVDS compatible output  
  • Supply voltage of 3.3V ±10%  
  • 25MHz input frequency  
  • HCSL outputs, 0.7V Current mode differential pair  
  • Jitter 60ps cycle-to-cycle (typ)  
  • Spread of ±0.25%, -0.5%, -0.75%, and no spread    
  • Industrial temperature range
  • Packaging: (Pb-free and Green)

        - 16-pin, 173 mils wide TSSOP
