PI6LC48P0405LIE

Overview

The PI6LC48P0405LIE is a four-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 0.14ps (1.875MHz–20MHz) and 0.32ps (12kHz–20MHz). The device supports selectable crystal oscillator interfaces or LVCMOS/LVTTL single-ended clock inputs. It operates with full 3.3V or 2.5V supply modes and functions within an industrial temperature range of -40°C to 85°C. The component is available in a lead-free 24-TSSOP package.

Feature Summary

• Four differential LVPECL output pairs
• Typical RMS phase jitter of 0.14ps at 125MHz (1.875MHz–20MHz bandwidth)
• Selectable crystal oscillator interface or LVCMOS/LVTTL single-ended clock input
• Supports 3.3V or 2.5V supply modes

Applications

• Networking systems

Procurement Notes

Verify the ordering suffix 'E' indicates tape and reel packaging and 'X' denotes tape and reel when applicable. Confirm 'L' signifies lead-free and green compliance. Ensure the specific variant matches the required packaging type for automated assembly processes.

Selection Notes

Select this component for applications requiring low phase jitter Ethernet clocks. Ensure power supply filtering techniques are implemented, including separate VDD, VDDA, and VDDO connections with appropriate bypass capacitors. Verify compatibility with 25MHz parallel resonant crystals if using the crystal interface mode.
