PI6LC48P0401LIE

Overview

The PI6LC48P0401LIE is a four-output LVPECL synthesizer from the HiFlex family, designed for Ethernet reference clock generation. It utilizes a 25MHz crystal or single-ended CMOS/LVTTL input to produce selectable frequencies of 156.25MHz, 125MHz, and 62.5MHz via N_SEL pins. The device employs low phase noise VCO technology, achieving typical RMS phase jitter of 0.23ps at 156.25MHz (1.875MHz–20MHz). It supports full 3.3V or 2.5V supply modes with an operating temperature range of -40°C to +85°C.

Feature Summary

• Four differential LVPECL output pairs
• Selectable 25MHz crystal or LVCMOS/LVTTL single-ended clock input
• Supports 156.25MHz, 125MHz, and 62.5MHz output frequencies
• Typical RMS phase jitter of 0.23ps at 156.25MHz (1.875MHz–20MHz)
• Full 3.3V or 2.5V supply voltage compatibility

Applications

• Networking systems
• Ethernet interface clocking

Procurement Notes

Verify that the ordering suffix 'LIE' corresponds to the industrial temperature grade (-40°C to +85°C) and lead-free green packaging as specified in the datasheet. Confirm the package type is 24-pin TSSOP. Ensure power supply filtering techniques are followed during implementation to maintain optimal jitter performance.

Selection Notes

Select this component when four differential LVPECL outputs are required for Ethernet applications. Choose based on the specific frequency need: 156.25MHz (N_SEL=00), 125MHz (N_SEL=01), or 62.5MHz (N_SEL=10). Verify compatibility with 2.5V or 3.3V system supplies. Consider the 24-pin TSSOP package constraints for PCB layout.
