PI6C4911510ZHIEX

Clock Buffers, Drivers Overview

The PI6C4911510ZHIEX is a high-performance, low-skew 1-to-10 LVPECL fanout buffer manufactured by Diodes Incorporated. It features two selectable differential clock inputs and translates them to ten LVPECL output pairs. The device supports input levels including LVPECL, LVDS, CML, and SSTL. It operates with core and output power supplies of 2.5V ±5% or 3.3V ±10%. Key electrical parameters include a maximum frequency (fmax) of 1500 MHz, a typical output skew of 40 ps, and an additive jitter of less than 0.03 ps RMS at 156.25 MHz. The component is housed in a 32-pin QFN package.

Clock Buffers, Drivers Feature Summary

• 1-to-10 LVPECL fanout buffer with two selectable differential clock inputs
• Low additive jitter performance (< 0.03 ps typ) and low output skew (40 ps typ)
• Supports LVPECL, LVDS, CML, and SSTL input signal levels
• Dual supply operation: Core VDD and Output VDDO both support 2.5V ±5% and 3.3V ±10%

Clock Buffers, Drivers Applications

• Clock distribution for low noise SaRonix-eCera oscillators
• High-speed digital systems requiring low jitter clock buffering

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'X' indicates Tape & Reel packaging when sourcing this specific part number. Confirm that the ZH package code corresponds to the 32-pin QFN form factor required for the design. Ensure compliance with Pb-free and Green material specifications as defined in the manufacturer's ordering information.

Clock Buffers, Drivers Selection Notes

Select the PI6C4911510ZHIEX when a 1-to-10 LVPECL fanout is required with minimal skew and jitter. The ZH suffix denotes the 32-pin QFN package; choose FA or FAE variants if TQFP packaging is preferred. Verify that the system power rails align with the 2.5V or 3.3V operating requirements for both core and output supplies.

Clock Buffers, Drivers Part Context

This component belongs to the PI6C4911510 series of low-skew fanout buffers. The ZHIEX variant specifically utilizes the ZH package code, which identifies the 32-pin Thin Quad Flat No-Lead (QFN) housing. The 'E' suffix confirms Pb-free and Green manufacturing, while 'X' specifies Tape & Reel delivery.

Clock Buffers, Drivers Replacement Considerations

The datasheet lists PI6C4911510ZHIE as the non-reel version of the same package. Other package variants within the family include PI6C4911510FAIEX (TQFP) and PI6C4911510FAEIEX (TQFP E-Pad). Cross-package substitution requires verifying footprint compatibility.
