PI6CFGL201BZDIE

Overview

The PI6CFGL201B is a low-power clock generator designed for PCIe Gen 1, 2, and 3 applications. It features an integrated PLL capable of generating a 100MHz output from a 25MHz crystal or reference input. The device provides two differential output pairs (CLK0 and CLK1) with selectable HCSL or LVDS compatibility, supporting programmable amplitude and slew rate control. It includes spread spectrum capabilities (-0.25%, -0.5%) and an SMBus interface for configuration. Operating on a 3.3V core supply and 1.8V output supply, it delivers typical cycle-to-cycle jitter of 30ps and phase jitter compliant with PCIe standards.

Feature Summary

• Generates 100MHz clock signals compliant with PCIe Gen 1, 2, and 3 specifications
• Supports 25MHz crystal or external reference clock inputs via XTAL_IN pin
• Provides two differential output pairs with configurable HCSL or LVDS signaling
• Includes spread spectrum modulation options (-0.25% and -0.5%) and SMBus configuration

Applications

• PCI Express Gen 1, 2, and 3 clock generation
• System board clock distribution for high-speed interfaces
• Low power server and workstation platforms

Procurement Notes

Verify the ordering suffix to confirm package type and reel quantity. The 'ZD' suffix indicates a 24-pin TQFN package, while adding an 'X' suffix specifies tape and reel packaging. Confirm that the specific variant matches the required industrial temperature range and lead-free compliance standards before procurement.

Selection Notes

Select this component when designing systems requiring a single-source 100MHz clock for multiple PCIe lanes. Ensure the design supports the required 3.3V and 1.8V supply rails. Verify that the load capacitance requirements for the 25MHz crystal align with the recommended C1/C2 values of 27pF for optimal frequency accuracy.
