PI6LC48P03LIEX

Overview

The PI6LC48P03LIEX is a 3-output LVPECL synthesizer from the HiFlex family, designed for Ethernet reference clock generation. It supports 2.5V or 3.3V supply modes and accepts either a 31.25MHz/26.041666MHz crystal or an LVCMOS/LVTTL single-ended input. The device generates selectable frequencies of 125MHz, 156.25MHz, 312.5MHz, and 625MHz via four frequency select pins. It features ultra-low phase jitter (0.3ps typical at 156.25MHz) and operates within -40°C to +85°C ambient temperature in a lead-free 24-TSSOP package.

Feature Summary

• Three differential LVPECL output pairs with configurable divider settings
• Ultra-low RMS phase jitter of 0.3ps (typical) at 156.25MHz (12kHz–20MHz)
• Supports both crystal oscillator interface and LVCMOS/LVTTL single-ended clock input
• Generates standard Ethernet frequencies: 125MHz, 156.25MHz, 312.5MHz, and 625MHz

Applications

• Networking systems
• Ethernet interface synchronization

Procurement Notes

Verify that the ordering suffix 'LIEX' corresponds to the Industrial temperature range (-40°C to +85°C), Pb-free/Green status, and Tape & Reel packaging configuration as specified in the datasheet ordering information section.

Selection Notes

Select this component when low phase jitter is critical for Ethernet applications. Ensure the design accommodates separate power supplies (VDD, VDDA, VDDO) and utilizes recommended filtering techniques, including 0.1μF bypass capacitors and isolation resistors for VDDA, to maintain optimal performance.
