PI6LC48C21LEX

Overview

The PI6LC48C21LEX is a single LVCMOS output clock synthesizer from the HiFlex family, designed to generate Ethernet reference frequencies. It utilizes a 25MHz crystal input to produce a 125MHz output with typical RMS phase jitter of 0.15ps (1.875MHz–20MHz) and 0.33ps (12kHz–20MHz). The device supports full 3.3V or 2.5V supply modes and operates within an industrial temperature range of -40°C to +85°C. Packaged in an 8-TSSOP format, it integrates separate analog and digital power supplies for noise isolation.

Feature Summary

• Single LVCMOS output generating 125MHz or 130MHz frequencies
• Low RMS phase jitter: 0.15ps typical at 125MHz (1.875MHz–20MHz bandwidth)
• Dual supply configuration supporting 3.3V or 2.5V operation
• Industrial ambient operating temperature range (-40°C to +85°C)

Applications

• Networking systems requiring Ethernet interface clocks

Procurement Notes

Verify the ordering code suffix 'EX' confirms tape and reel packaging. Confirm the 'L' suffix indicates lead-free and green compliant materials. Ensure the specific variant matches the required voltage domain (3.3V or 2.5V) and package width specifications.

Selection Notes

Select this component when a single-ended LVCMOS Ethernet reference clock is required. It is suitable for designs needing low jitter performance with a 25MHz crystal input. Consider the separate VDDA and VDD pins for proper power supply filtering techniques to maintain optimal jitter characteristics.
