PI6LC48P0301AZHIE

Overview

The PI6LC48P0301AZHIE is a 3-output LVPECL synthesizer from the HiFlex family, designed for Ethernet reference clock generation. It operates on 2.5V or 3.3V supplies and accepts a 25MHz crystal or CMOS/LVTTL input. The device generates frequencies of 125MHz, 156.25MHz, 312.5MHz, and 625MHz via four frequency select pins. RMS phase jitter is typically 0.26ps at 156.25MHz (12kHz–20MHz). It features separate power domains for core, analog, and output banks to minimize noise coupling.

Feature Summary

• Three differential LVPECL output pairs with selectable divider settings
• Ultra-low phase jitter: 0.26ps typical at 156.25MHz (12kHz–20MHz)
• Dual supply modes supporting full 2.5V or 3.3V operation
• Configurable via FBN, NA_SEL, and NB_SEL pins for multiple Ethernet frequencies

Applications

• Networking systems requiring precise Ethernet clocking
• Ethernet interface synchronization in industrial equipment
• High-performance data communication infrastructure

Procurement Notes

Verify the 'E' suffix confirms Pb-free and Green packaging status. Confirm the 'I' suffix indicates Industrial ambient operating temperature range (-40°C to +85°C). Ensure the 'X' suffix is present if tape and reel packaging is required; otherwise, standard tube packaging applies.

Selection Notes

Select this component when low phase jitter is critical for Ethernet applications. Choose between 2.5V or 3.3V based on system power availability. Use the frequency select pins to configure specific outputs like 156.25MHz or 625MHz. Ensure proper power supply filtering with 0.1μF bypass capacitors for each VDD pin to maintain jitter performance.
