PI6LC4830ZHEX

Overview

The PI6LC4830ZHEX is a HiFlex network clock generator designed for PCIe 2.0 applications, utilizing an LC VCO architecture to achieve low phase noise performance. It operates on a single 3.3V supply and features a 32-lead 5x5mm TQFN package. The device provides three HCSL outputs at 100MHz and two LVCMOS outputs (one fixed at 100MHz, one selectable at 100/50MHz). A differential 25MHz input or crystal oscillator supports the PLL, which delivers a maximum integrated phase noise of 1ps RMS.

Feature Summary

• LC VCO based design with max 1ps RMS integrated phase noise
• Three 100MHz HCSL outputs and two LVCMOS outputs (100MHz / 100-50MHz selectable)
• Supports 25MHz crystal or differential IN+/IN- inputs
• Single 3.3V power supply operation

Applications

• PCIe 2.0 compliant systems
• Demanding high-speed networking environments

Procurement Notes

Verify that the ordering suffix 'ZH' corresponds to the 32-pin TQFN package and 'E' indicates Pb-free/Green status. Confirm if the 'X' suffix is required for Tape/Reel packaging, as the datasheet notes this addition changes the shipping format. Ensure the component meets RoHS3 compliance requirements for your specific manufacturing process.

Selection Notes

Select this component when ultra-low noise margins are critical for noisy environments. The LC VCO technology offers superior noise performance compared to traditional solutions. Ensure the design accommodates the 3.3V supply voltage range of 2.9V to 3.6V and utilizes the recommended external crystal specifications (CL=18pF) for optimal frequency stability.
