PI6LC48P0301AZHEX

Overview

The PI6LC48P0301AZHEX is a 3-output LVPECL synthesizer from Diodes Incorporated, part of the HiFlex family. It generates Ethernet reference clock frequencies using a 25MHz crystal or single-ended LVCMOS/LVTTL input. The device supports output frequencies of 125MHz, 156.25MHz, 312.5MHz, and 625MHz. RMS phase jitter at 156.25MHz is typically 0.26ps (max 0.4ps) with a 25MHz crystal. It operates on full 3.3V or 2.5V supplies in a lead-free 28-TQFN package.

Feature Summary

• Three differential LVPECL output pairs
• Supports 125MHz, 156.25MHz, 312.5MHz, and 625MHz outputs
• Ultra-low RMS phase jitter: 0.26ps typical at 156.25MHz (12kHz–20MHz)
• Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended clock input

Applications

• Networking systems
• Ethernet interface applications

Procurement Notes

Verify the ordering suffix 'ZH' corresponds to the commercial temperature range and 'E' indicates Pb-free/Green status. Confirm tape and reel packaging by checking for an appended 'X'. Ensure the specific variant matches the required operating temperature range before procurement.

Selection Notes

Select based on required output frequency divider settings via NA_SEL and NB_SEL pins. Verify power supply requirements (3.3V or 2.5V). For crystal inputs, ensure compatibility with fundamental mode crystals (e.g., 25MHz, 18pF load capacitance). Check thermal resistance values if high ambient temperatures are expected.

Part Context

This component belongs to the PI6LC48P0301A series within Diodes Incorporated's HiFlex portfolio. It is designed as a high-performance networking clock generator optimized for low phase noise applications, specifically targeting Ethernet reference clock generation needs.
