PI6LC48S25AZBBIE

Overview

The PI6LC48S25AZBBIE is a Next Generation HiFlex Ethernet Network Clock Generator designed for 10GbE applications. It features an LC VCO-based low phase noise design with a typical integrated phase jitter of 0.3ps RMS at 156.25MHz (12kHz to 20MHz). The device supports 3.3V and 2.5V supply voltages, accepting 25MHz crystal or differential inputs (25MHz, 125MHz, 156.25MHz). It provides four output banks generating frequencies up to 312.5MHz in LVPECL or LVDS formats. Configuration is managed via pin selection or an I2C interface.

Feature Summary

• Low phase noise LC VCO design with 0.3ps typical integrated phase jitter at 156.25MHz
• Four output banks supporting selectable LVPECL or LVDS signaling
• Dual configuration options: Pin selection and I2C serial interface
• Supports 3.3V and 2.5V power supplies with industrial temperature range (-40°C to 85°C)

Applications

• 10 Gigabit Ethernet (10GbE) systems
• Ethernet network clock generation

Procurement Notes

Verify the component matches the specific datasheet revision A documentation from Diodes Incorporated. Confirm that the ZBB package code corresponds to the 56-lead 8x8mm TQFN form factor. Ensure the ordering suffix 'E' aligns with the Pb-free and Green material specifications defined in the manufacturer's ordering information.

Selection Notes

Select this component when designing for 10GbE interfaces requiring ultra-low phase jitter. Choose between pin-selectable or I2C-controlled operation based on system flexibility needs. Ensure the target application supports either 3.3V or 2.5V core and output supply rails. Verify that the required output frequencies (up to 312.5MHz) and signaling standards (LVPECL/LVDS) are compatible with the connected receivers.
