PI6LC48P04LIEX

Overview

The PI6LC48P04LIEX is a four-output LVPECL synthesizer from Diodes Incorporated's HiFlex family, designed for Ethernet and Fibre Channel reference clock generation. It supports dual supply modes of 3.3V or 2.5V with typical power consumption of 130mA at 3.3V. The device generates frequencies including 212.5MHz, 159.375MHz, 106.25MHz, 53.125MHz, 156.25MHz, and 187.5MHz using 26.5625MHz or 26.04166MHz crystals. It achieves less than 1ps typical RMS phase jitter (0.3ps at 212.5MHz) and operates within an ambient temperature range of -40°C to +85°C in a 24-pin TSSOP package.

Feature Summary

• Four differential LVPECL output pairs optimized for networking applications
• Supports selectable crystal oscillator interface or single-ended LVCMOS/LVTTL input
• Generates specific Ethernet/Fibre Channel frequencies via two N_SEL pins
• Ultra-low phase noise VCO technology achieving <1ps typical RMS jitter

Applications

• Networking systems
• Ethernet interfaces
• Fibre Channel systems

Procurement Notes

Verify the ordering suffix 'E' confirms tape and reel packaging for the PI6LC48P04LIEX variant. Confirm the component meets Pb-free and Green specifications as indicated in the manufacturer's ordering information. Ensure the selected frequency select pin settings align with the required output frequencies listed in the datasheet function table.

Selection Notes

Select this component when four synchronized LVPECL outputs are required for high-speed serial links. Verify that the system can accommodate separate 3.3V or 2.5V supplies for core, analog, and output domains. Consider the 24-TSSOP package dimensions and thermal characteristics if operating near the upper temperature limit of 85°C.
