PI6LC48P0301LE

Overview

The PI6LC48P0301LE is a 3-output LVPECL synthesizer from the HiFlex family, designed for Ethernet reference clock generation. It supports 3.3V or 2.5V supply modes and operates within -40°C to +85°C. The device generates frequencies of 125MHz, 156.25MHz, 312.5MHz, and 625MHz using a 19.53125MHz or 25MHz crystal or an LVCMOS/LVTTL input. Key electrical parameters include RMS phase jitter of 0.16ps (typical) at 156.25MHz (1.875MHz–20MHz bandwidth) with a 25MHz crystal. It features selectable output dividers via hardware pins and is housed in a lead-free 24-TSSOP package.

Feature Summary

• Three differential LVPECL output pairs optimized for Ethernet applications
• Ultra-low phase jitter: 0.16ps typical RMS at 156.25MHz (1.875MHz–20MHz)
• Supports 125MHz, 156.25MHz, 312.5MHz, and 625MHz output frequencies
• Selectable crystal oscillator interface or single-ended LVCMOS/LVTTL input

Applications

• Networking systems
• Ethernet interface circuits

Procurement Notes

Verify the ordering suffix 'LE' confirms the Pb-free, Green status and commercial temperature range (-40°C to +85°C). Confirm the package type is 24-pin TSSOP. Ensure the specific revision matches design requirements, as datasheet revisions may update electrical characteristics or pin definitions.

Selection Notes

Select this component when low phase jitter is critical for Ethernet links. Choose between the LE (Commercial) and LIE (Industrial) suffixes based on ambient operating temperature requirements. Verify that the system power rails align with the supported 2.5V or 3.3V full supply modes.

Part Context

This part belongs to Pericom’s HiFlex family of high-performance clock solutions, now under Diodes Incorporated. It utilizes proprietary low phase noise PLL technology to minimize jitter, distinguishing it from standard clock generators by its focus on ultra-low phase noise performance for high-speed networking interfaces.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching LVPECL outputs, frequency ranges, and jitter specifications.
