Product Description

The PI6C557-01B is a spread spectrum clock generator compli- ant to PCI Express® 3.0 and Ethernet requirements. The device is used for PC or embedded systems to substantially reduce Electro- magnetic Interference (EMI).

The PI6C557-01B provides one differential (HCSL) or LVDS spread spectrum output. Using Diodes' patented Phase-Locked Loop (PLL) techniques, the device takes a 25MHz crystal input and produces one pair of differential outputs (HCSL) at 100MHz. It also provides spread selection of -0.5% and no spread.

  • HCSL outputs, 0.8V Current mode differential pair
  • Jitter 35ps cycle-to-cycle (typ)
  • Spread of -0.5% and no spread
  • Industrial temperature range
  • Spread Bypass option available
  • Spread selection via external pins
  • Packaging: (Pb-free and Green)

      - 16-pin TQFN
