PI6LC48P0101LIE

Overview

The PI6LC48P0101LIE is a HiFlex 10GbE clock generator from Diodes Incorporated, packaged in an 8-pin TSSOP. It generates differential LVPECL outputs with frequencies of 312.5MHz or 625MHz, selected via the FREQ_SEL pin. The device supports 2.5V or 3.3V supplies and utilizes an 18pF parallel resonant crystal (23.2MHz–30MHz). RMS phase jitter is typically 0.3ps at 312.5MHz (12kHz–20MHz) and 0.3ps at 625MHz. Operating temperature ranges from -40°C to 85°C.

Feature Summary

• Single differential LVPECL output pair
• Output frequency selectable between 312.5MHz and 625MHz
• Supports 18pF parallel resonant crystals (23.2MHz–30MHz)
• Ultra-low RMS phase jitter: 0.3ps typical (12kHz–20MHz)

Applications

• 10 Gigabit Ethernet systems
• Networking equipment requiring low-jitter reference clocks

Procurement Notes

Verify the ordering suffix 'LIE' corresponds to the Pb-free, Green, 8-pin TSSOP package in tape and reel format. Confirm supply voltage requirements match the target system's 2.5V or 3.3V rails. Ensure power supply filtering techniques, including separate VDD/VDDA bypassing, are implemented to maintain specified jitter performance.

Selection Notes

Select this component for applications requiring a single LVPECL output derived from a crystal oscillator. The fixed M/N ratio of 25/1 determines the multiplication factor. Verify that the input crystal falls within the 23.2MHz to 30MHz range and has an 18pF load capacitance. Check thermal resistance values if board space is constrained.

Part Context

This part belongs to the HiFlex family of high-performance clock solutions designed for networking applications. It integrates a PLL and VCO to synthesize precise frequencies from a low-frequency crystal reference. The device simplifies design by providing a complete clock generation solution in a small footprint.

Replacement Considerations

Check for updated revisions or alternative packages within the PI6LC48 series. Ensure any substitute maintains the same LVPECL output type and jitter specifications. Verify pin compatibility if replacing in an existing layout.
