PI6LC48P25104LIE

Overview

The PI6LC48P25104LIE is a single-output LVPECL clock synthesizer from the HiFlex family, designed for Ethernet reference clock generation. It operates on 3.3V or 2.5V supplies and accepts a 25MHz crystal input to generate 156.25MHz or 187.5MHz outputs via Freq_SEL selection. The device utilizes low phase noise PLL technology, achieving an RMS phase jitter of 0.3ps (typical) at 156.25MHz within the 12kHz-20MHz bandwidth. Packaged in an 8-TSSOP, it supports commercial and industrial temperature ranges.

Feature Summary

• Single differential LVPECL output with frequency range of 145MHz to 187.5MHz
• Ultra-low RMS phase jitter: 0.3ps typical at 156.25MHz (12kHz-20MHz)
• Dual supply mode support: 3.3V or 2.5V operation
• Freq_SEL pin allows selection between 156.25MHz and 187.5MHz using a 25MHz crystal

Applications

• Networking systems
• Servers and storage systems
• SATA/SAS interfaces
• Ethernet interface applications

Procurement Notes

Verify the 'I' suffix indicates the Industrial operating temperature range (-40°C to +85°C). Confirm the package is lead-free and green compliant. Ensure the ordering code matches the specific packaging requirements, as adding an 'X' denotes tape and reel packaging.

Selection Notes

Select this component when a single-ended LVPECL output is required for high-speed networking or storage interfaces. Use the Freq_SEL pin to toggle between 156.25MHz and 187.5MHz frequencies based on the system's 25MHz crystal input. Ensure power supply filtering techniques are applied to maintain optimal jitter performance.
