PI6LC48S25AZBBIEX

Overview

The PI6LC48S25AZBBIEX is a Next Generation HiFlex Ethernet Network Clock Generator designed for 10GbE applications. It features an LC VCO-based low phase noise design with 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 (25/125/156.25MHz). It provides four output banks generating frequencies up to 312.5MHz in LVPECL or LVDS formats, plus a CMOS output. Configuration is managed via pin selection or I2C interface.

Feature Summary

• Low Phase Noise: 0.3ps typical integrated phase jitter at 156.25MHz
• Flexible Input: Supports 25MHz crystal or differential inputs (LVPECL/LVDS/CML/HCSL)
• Multi-Bank Outputs: Four banks (A/B/C/D) with selectable LVPECL or LVDS signaling
• Programmable Frequencies: Generates 312.5, 156.25, 125, 100, 50, and 25MHz
• Dual Control: Pin selection and I2C interface for configuration

Applications

• 10 Gigabit Ethernet (10GbE) systems
• Ethernet network clock generation
• Embedded networking systems requiring low jitter clocks

Procurement Notes

Verify the 'ZBB' package code corresponds to the 56-lead 8x8mm TQFN form factor. Confirm the 'IEX' suffix indicates Tape & Reel packaging as specified in the ordering information. Ensure the component meets industrial temperature requirements (-40°C to 85°C) for the target application environment.

Selection Notes

Select this model when 10GbE compliance and ultra-low phase noise are critical. Choose between pin-selectable or I2C-controlled variants based on system flexibility needs. Ensure power supply rails match the 3.3V or 2.5V specifications. Verify that the required output frequencies (up to 312.5MHz) and signaling types (LVPECL/LVDS) align with the receiver inputs.

Part Context

This part belongs to the Pericom (now Diodes Incorporated) HiFlex family of clock generators. It is specifically engineered for high-performance networking applications where signal integrity and timing precision are paramount. The device integrates multiple PLLs and buffers into a single compact package to reduce board space.

Replacement Considerations

Check for updated revisions from Diodes Incorporated. Verify pin compatibility if substituting with other HiFlex models like the PI6LC48 series. Ensure the replacement supports the same 56-pin TQFN package and thermal characteristics.
