PI6LC48L0201LIEX

Overview

The PI6LC48L0201LIEX is a two-output LVDS synthesizer from the HiFlex family, designed for Ethernet reference clock generation. It supports output frequencies of 62.5MHz, 125MHz, and 156.25MHz using a 25MHz crystal or single-ended CMOS/LVTTL input. The device utilizes proprietary low phase noise PLL technology to achieve ultra-low jitter, with typical RMS phase jitter of 0.2ps (1.875MHz–20MHz) at 156.25MHz. It operates on full 3.3V or 2.5V supply modes and is available in a lead-free 20-TSSOP package.

Feature Summary

• Two differential LVDS output pairs optimized for Ethernet applications
• Selectable 25MHz crystal oscillator interface or LVCMOS/LVTTL single-ended clock input
• Ultra-low phase jitter: 0.2ps typical RMS (1.875MHz–20MHz) at 156.25MHz
• Supports 3.3V or 2.5V supply voltages with commercial and industrial temperature ranges

Applications

• Networking systems requiring Ethernet reference clocks

Procurement Notes

Verify the ordering suffix 'LIEX' corresponds to the Industrial temperature range (-40°C to +85°C) and Tape & Reel packaging as specified in the datasheet. Confirm RoHS compliance and Green status. Ensure the component matches the 20-TSSOP physical dimensions and pinout configuration before integration.

Selection Notes

Select this component when generating standard Ethernet frequencies (62.5MHz, 125MHz, 156.25MHz) with strict jitter requirements. Use N_SEL pins to configure the desired output frequency. Ensure power supply filtering includes 0.1μF bypass capacitors for VDD/VDDA/VDDO and appropriate isolation resistors for VDDA to maintain optimal jitter performance.

Part Context

This part belongs to Pericom’s HiFlex family of high-performance clock solutions, now manufactured by Diodes Incorporated. It is specifically engineered to replace legacy clock generators in networking equipment, offering a compact solution for generating precise Ethernet reference signals with minimal footprint.

Replacement Considerations

Check pin compatibility and electrical characteristics against existing designs. Verify that the target system supports LVDS outputs and the required supply voltage (3.3V or 2.5V). Ensure the replacement package (20-TSSOP) fits the PCB layout constraints.
