PI6LC48P02LIE

Overview

The PI6LC48P02LIE is a 2-output LVPECL synthesizer from Diodes Incorporated’s HiFlex family, designed for Fibre Channel, Ethernet, and storage reference clock generation. It supports dual supply modes of 3.3V or 2.5V and operates within an industrial temperature range of -40°C to +85°C. The device utilizes proprietary low phase noise PLL technology to achieve ultra-low jitter, with typical RMS phase jitter ranging from 0.17ps to 0.60ps depending on frequency and bandwidth. It features selectable crystal oscillator interfaces (25MHz, 26.041667MHz, 26.5625MHz) or single-ended CMOS/LVTTL inputs.

Feature Summary

• Two differential LVPECL output pairs optimized for networking and storage applications
• Supports multiple output frequencies including Ethernet (50-200MHz) and Fibre Channel (53.125-212.5MHz)
• Ultra-low RMS phase jitter: 0.28ps typical at 212.5MHz (12kHz–20MHz) using 26.5625MHz crystal
• Selectable input via crystal pins (XTAL_IN/OUT) or single-ended Ref_IN pin

Applications

• Networking and Data Center Server systems
• Fibre Channel (FC) and Storage systems
• Ethernet interface clock generation

Procurement Notes

Verify the ordering suffix 'LIE' corresponds to the Pb-free, Green, 20-pin TSSOP package in tape and reel format. Confirm the manufacturer is Diodes Incorporated, as the datasheet references Pericom Semiconductor Corporation prior to acquisition. Ensure the component meets RoHS3 compliance standards for the specific batch.

Selection Notes

Select this component when low phase jitter is critical for Fibre Channel or high-speed Ethernet links. Choose between 3.3V or 2.5V supply based on system voltage requirements. Use N_SEL pins to configure specific output frequencies without external programming. Ensure proper power supply filtering with 0.1μF bypass capacitors and isolation resistors for VDDA to maintain jitter performance.

Part Context

The PI6LC48P02 belongs to the HiFlex family of high-performance clock solutions. The 'LIE' suffix indicates a lead-free, green compliant version packaged in a 20-pin TSSOP with tape and reel delivery. This part is functionally equivalent to the PI6LC48P02LIEX, differing only in packaging quantity configuration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB layout regarding the 20-TSSOP footprint and thermal resistance characteristics (QJA 84.0°C/W).
