PI6C4911510-05FAIEX

Clock Buffers, Drivers Overview

The PI6C4911510-05FAIEX is a high-performance, low-skew 1-to-10 LVPECL/ECL fanout buffer manufactured by Diodes Incorporated. It translates differential clock inputs into ten differential LVPECL outputs. The device supports maximum frequencies up to 1.5 GHz with a typical propagation delay of 1200 ps and output skew under 55 ps. It features selectable differential input pairs (CLK0/CLK1) or single-ended options, accepting LVPECL, LVDS, CML, and SSTL signal levels. Power supply ranges include 3.3V ±10% or 2.5V ±5%, operating within -40°C to +85°C in a 32-pin TQFP package.

Clock Buffers, Drivers Feature Summary

• Telecommunications equipment

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'X' indicates tape and reel packaging when sourcing this component. Confirm that the 'E' suffix denotes Pb-free and Green material compliance as specified in the datasheet. Ensure the supplier provides documentation confirming the 32-pin TQFP package type (Code FA). Cross-reference the manufacturer number with Diodes Incorporated or Pericom Semiconductor records.

Clock Buffers, Drivers Selection Notes

Select this component when a 1-to-10 fanout ratio with LVPECL outputs is required. It is suitable for applications needing low additive jitter (< 0.03 ps typ) and tight output skew (< 55 ps max). The device accommodates both 2.5V and 3.3V power supplies. Consider the SYNC_OE feature if synchronized clock enable/disable functionality is necessary for the system design.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C4911510 series of fanout buffers. It is designed to provide high-speed clock distribution with minimal skew. The device integrates two selectable differential clock inputs and ten differential outputs, making it a versatile solution for complex clock tree architectures in high-frequency applications.

Clock Buffers, Drivers Replacement Considerations

Check for direct pin-compatible alternatives within the same family, such as variants with different output counts or packaging options. Verify electrical parameters like frequency limits and voltage ranges match the original design requirements before substitution.
