The 557-03 is a spread spectrum clock generator that supports PCI-Express Gen 1 and Ethernet requirements. The device is used for PC or embedded systems to substantially reduce electromagnetic interference (EMI). The device provides two differential (HCSL) spread spectrum outputs. The spread type and amount are configured via select pin. Using IDT's patented Phase-Locked Loop (PLL) techniques, the device takes a 25 MHz crystal input and produces two pairs of differential outputs at 25 MHz, 100 MHz, 125 MHz or 200 MHz clock frequencies for HCSL, and 25 MHz or 100 MHz for LVDS.

Features

  • Packaged in 16-pin TSSOP
  • RoHS 5 (green) or RoHS 6 (green and lead free) compliant packaging
  • Supports HCSL or LVDS output levels
  • Operating voltage of 3.3 V
  • Input frequency of 25 MHz
  • Jitter 60 ps (cycle-to-cycle)
  • Spread Spectrum capability
  • Industrial and commercial temperature ranges
  • For PCIe Gen2 applications, see the 5V41065
  • For PCIe Gen3 applications, see the 5V41235
