PI6LC4830ZHE

Overview

The PI6LC4830ZHE is a HiFlex network clock generator from Diodes Incorporated, designed for demanding PCIe 2.0 applications. It utilizes an LC VCO architecture to achieve low phase noise performance. The device provides three HCSL outputs and two LVCMOS outputs at 100MHz, with one LVCMOS output selectable between 100MHz and 50MHz. It accepts a 25MHz crystal or differential input and features a PLL bypass mode. Operating on a single 3.3V supply, it delivers a maximum RMS integrated phase noise of 1ps within the 12kHz-20MHz range.

Feature Summary

• Three 100MHz HCSL outputs and two LVCMOS outputs (one selectable 100/50MHz)
• Ultra-low phase noise design with max 1ps RMS integrated jitter
• Supports 25MHz crystal or differential IN+/IN- inputs
• PLL bypass mode available for testing

Applications

• PCIe 2.0 reference clock generation
• High-performance networking equipment
• Data communication systems requiring low jitter

Procurement Notes

Verify the package code ZH corresponds to the 32-pin TQFN form factor. Confirm RoHS compliance status via the manufacturer's documentation. Check for specific ordering suffixes such as 'X' which indicates tape and reel packaging versus standard tube packaging.

Selection Notes

Select this component when a 3.3V supply is required for PCIe 2.0 designs. Ensure the PCB layout accommodates the 5x5mm TQFN footprint. Verify that the input source matches the supported 25MHz crystal or differential signal specifications.
