PI6LC48L0201AZHIEX

Overview

The PI6LC48L0201AZHIEX is a 2-output LVDS synthesizer optimized for Ethernet reference clock frequencies. It utilizes a proprietary low phase noise PLL to achieve ultra-low jitter, supporting output frequencies of 62.5MHz, 125MHz, and 156.25MHz using a 25MHz crystal input. The device operates on full 3.3V or 2.5V supplies with an industrial temperature range (-40°C to +85°C). RMS phase jitter at 156.25MHz is typically 0.3ps (max 0.5ps) within the 12kHz–20MHz bandwidth. It features selectable crystal or single-ended CMOS/LVTTL inputs and is housed in a lead-free 20-TQFN package.

Feature Summary

• Two differential LVDS output pairs
• Supports 62.5MHz, 125MHz, and 156.25MHz outputs via N_SEL pins
• Ultra-low RMS phase jitter: 0.3ps typical at 156.25MHz (12kHz-20MHz)
• Selectable 2.5V or 3.3V supply modes

Applications

• Networking systems
• Ethernet interface applications

Procurement Notes

Verify the ordering suffix 'E' indicates Pb-free and Green compliance, and 'X' denotes tape and reel packaging. Confirm the specific package type matches the design requirements, as the base model may be available in tube packaging. Ensure the component meets RoHS standards for the target market.

Selection Notes

Select this component when generating standard Ethernet reference clocks (62.5/125/156.25MHz) with strict jitter requirements. Use the N_SEL pins to configure the desired output frequency from a 25MHz crystal source. Ensure power supply filtering includes 0.1μF bypass capacitors and consider the separate VDDA pin isolation for optimal performance.

Part Context

This part belongs to the HiFlex family of high-performance clock solutions by Pericom Semiconductor Corporation (now Diodes Incorporated). It is specifically designed to replace older clock generators in networking equipment requiring precise timing and low jitter characteristics for Ethernet interfaces.
