DIOPI6C557-01BZHIEX
Overview
The PI6C557-01BZHIEX is a low-jitter PCIe clock generator designed to provide high-performance timing for PCI Express and Ethernet systems. Operating from a 3.0V to 3.6V supply, this device supports both HCSL and LVDS output signaling with a fixed 100MHz frequency. It features integrated spread spectrum capabilities to mitigate electromagnetic interference (EMI) in high-speed digital designs.
Why Choose This Part
This IC offers PCIe 3.0 compliance with flexibility between HCSL and LVDS output types. It includes a spread spectrum option of -0.5% or no spread, selectable via external pins, allowing engineers to optimize for EMI reduction or maximum signal integrity. The compact 3x3mm TQFN-16 package minimizes PCB footprint while maintaining industrial temperature reliability.
Applications
Key Specifications
Getting Started
When designing with this part, ensure the 100MHz crystal or reference input meets the specified stability requirements for PCIe compliance. Use high-quality decoupling capacitors near the VDD pins and follow HCSL/LVDS differential pair routing guidelines for 100-ohm or 85-ohm impedance. Spread spectrum settings should be configured via the SS_EN and SSEL pins during the hardware design phase.
