Overview

The PI6CG18401ZHIEX is a low-power, four-output HCSL clock generator designed specifically for 100MHz PCIe clocking applications. It operates from a 1.7V to 1.9V supply and features on-chip termination to reduce component count and PCB footprint.

Why Choose This Part

This IC integrates on-chip termination for four differential HCSL outputs, significantly simplifying impedance matching and saving board space. It offers programmable slew rates and spread-spectrum options (0%, -0.25%, or -0.5%) to assist in EMI compliance while maintaining a very low typical power consumption of 31mA total during 100MHz operation.

Applications

PCI Express Clocking
Providing high-precision 100MHz reference clocks for PCIe Gen1, Gen2, Gen3, and Gen4 systems.
Network Storage
Distributing low-jitter clock signals to multiple controllers in server and storage environments.
Embedded Computing
Synchronizing high-speed serial links in compact industrial computers using its 5x5mm TQFN package.

Getting Started

Configuration is handled via SMBus or physical strapping pins to set the output enable states and spread spectrum modes. Ensure the 32-VFQFN exposed pad is soldered to a solid ground plane for thermal dissipation and electrical performance. Design for a 1.8V nominal supply and use 25MHz crystal input as the frequency reference.
