PI6LC48P0405LIEX

Overview

The PI6LC48P0405LIEX is a 4-output LVPECL synthesizer from Diodes Incorporated’s HiFlex family, optimized for generating 125MHz clock frequencies. It utilizes proprietary low phase noise VCO technology to achieve typical RMS phase jitter of 0.32ps (12kHz–20MHz) and 0.14ps (1.875MHz–20MHz). The device supports selectable crystal oscillator or single-ended LVCMOS/LVTTL inputs and operates on full 3.3V or 2.5V supply modes within an industrial temperature range of -40°C to 85°C.

Feature Summary

• Four differential LVPECL output pairs
• Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended clock input
• Supports 125MHz output frequency with ultra-low phase jitter
• Full 3.3V or 2.5V supply mode compatibility

Applications

• Networking systems

Procurement Notes

Verify the ordering suffix 'X' confirms tape and reel packaging for the PI6LC48P0405LIEX variant. Confirm RoHS compliance status via official documentation before procurement. Ensure power supply filtering techniques are implemented as specified in the datasheet to maintain optimal jitter performance.

Selection Notes

Select this component when four independent LVPECL outputs at 125MHz are required. Verify that the system can accommodate either a 25MHz parallel resonant crystal or a single-ended reference input. Ensure the design supports separate VDD, VDDA, and VDDO power planes to isolate switching noise from the internal PLL.

Part Context

This part belongs to the PI6LC48 series of high-performance networking clock generators manufactured by Diodes Incorporated (formerly Pericom Semiconductor). It is designed specifically for Ethernet interfaces requiring precise timing signals with minimal phase noise.
