PI6C49X0208ZHIE

Clock Buffers, Drivers Overview

The PI6C49X0208ZHIE is a high-performance multi-voltage CMOS fanout buffer featuring an integrated crystal oscillator. It provides eight single-ended outputs and supports input frequencies up to 200 MHz when using an external clock source, or 10–50 MHz via the internal oscillator. The device operates with core supply voltages of 2.5 V or 3.3 V and allows user-configurable output supply voltages (VDDO) ranging from 1.2 V to 3.3 V. Key electrical characteristics include an ultra-low additive jitter of 0.01 ps typical and output skew of approximately 50 ps typical.

Clock Buffers, Drivers Feature Summary

• Integrated crystal oscillator supporting 10 MHz to 50 MHz inputs
• Eight single-ended CMOS outputs with selectable VDDO levels (1.2V–3.3V)
• Ultra-low additive RMS phase jitter of 0.01 ps typical
• Supports differential, single-ended, and crystal reference inputs

Clock Buffers, Drivers Applications

• Networking systems including switches and routers
• High-frequency backplane-based computing platforms
• Telecom infrastructure requiring low jitter clock distribution

Clock Buffers, Drivers Procurement Notes

Verify the component origin as Diodes Incorporated, which acquired Pericom Semiconductor. Confirm that the ZHIE suffix corresponds to the Pb-free, green 32-pin TQFN package in tape and reel format. Ensure the datasheet revision matches the specific manufacturing lot requirements for your design.

Clock Buffers, Drivers Selection Notes

Select this component when a system requires distributing a clock signal to eight destinations with varying voltage levels. The configurable VDDO banks allow mixing core voltages (2.5V/3.3V) with lower output voltages (1.2V, 1.5V, 1.8V). Ensure the input source matches the selected IN_SEL configuration for either crystal or external clock operation.

Clock Buffers, Drivers Part Context

This part belongs to the PI6C49X series of multi-voltage clock buffers. The 'ZH' package code denotes a 32-pin Thin Quad Flat No-Lead (TQFN) form factor. The 'E' suffix indicates lead-free and green material compliance, while 'X' specifies tape and reel packaging.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include the PI6C49X0208ZHIEX. Verify pin compatibility and electrical specifications against the target application requirements before substitution.
