PI6LC48P0301AZHIEX

Overview

The PI6LC48P0301AZHIEX is a 3-output LVPECL synthesizer from Diodes Incorporated’s HiFlex family, optimized for Ethernet reference clock generation. It supports output frequencies of 125MHz, 156.25MHz, 312.5MHz, and 625MHz using a 25MHz crystal or single-ended CMOS/LVTTL input. The device features ultra-low phase jitter, with typical RMS values of 0.26ps at 156.25MHz (12kHz–20MHz). It operates on full 3.3V or 2.5V supplies and is housed in a lead-free 28-TQFN package.

Feature Summary

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

Applications

• Networking systems

Procurement Notes

Verify the ordering suffix 'ZHIEX' corresponds to the Industrial temperature range (-40°C to +85°C) and Tape & Reel packaging as defined in the datasheet. Confirm RoHS compliance and Green status. Ensure power supply filtering techniques are applied to achieve specified jitter performance.

Selection Notes

Select this component when low phase jitter is critical for Ethernet interfaces. Use Bank A divider settings (NA_SEL) and Bank B divider settings (NB_SEL) via control pins to configure specific output frequencies. Ensure proper power supply isolation using separate VDD, VDDA, and VDDO pins with appropriate bypass capacitors.

Part Context

This part belongs to the PI6LC48 series of high-performance clock solutions. It utilizes proprietary low phase noise PLL technology. The 'ZHIEX' designation indicates an industrial grade variant packaged in a 28-pin TQFN format with tape and reel delivery.
