PI6LC48P0201AZHIE

Overview

The PI6LC48P0201AZHIE is a 2-output LVPECL synthesizer optimized for Ethernet reference clock generation, belonging to the HiFlex family. It utilizes proprietary low phase noise PLL technology to achieve ultra-low jitter. The device supports output frequencies of 62.5MHz, 125MHz, and 156.25MHz using a 25MHz crystal or single-ended LVCMOS/LVTTL input. It operates on full 3.3V or 2.5V supply modes within an industrial temperature range (-40°C to +85°C). RMS phase jitter at 156.25MHz is typically 0.3ps (max 0.5ps) over a 12kHz–20MHz bandwidth. The component is housed in a lead-free 20-TQFN package.

Feature Summary

• Two differential LVPECL output pairs with selectable frequency settings via N_SEL pins
• Ultra-low phase jitter: 0.3ps typical (12kHz–20MHz) at 156.25MHz using a 25MHz crystal
• Flexible input options including 25MHz crystal oscillator interface or LVCMOS/LVTTL single-ended clock
• Supports dual voltage supplies: 3.3V ±10% or 2.5V ±5%

Applications

• Networking systems requiring Ethernet reference clocks
• Embedded systems utilizing high-performance clock solutions

Procurement Notes

Verify the ordering suffix ZHIE confirms the specific 20-pin TQFN package with tape and reel packaging. Ensure compatibility with industrial temperature specifications (-40°C to +85°C) required for the target application environment before procurement.

Selection Notes

Select this component when generating standard Ethernet frequencies (62.5MHz, 125MHz, 156.25MHz) with strict jitter requirements. Confirm that the system design accommodates separate power supplies (VDD, VDDA, VDDO) for optimal noise isolation as specified in the datasheet.

Part Context

This part is manufactured by Diodes Incorporated under the Pericom brand and belongs to the HiFlex family of high-performance clock solutions. It is designed to minimize board area while providing multi-frequency outputs for networking platforms.

Replacement Considerations

The PI6LC48P0201AZHIEX is the identical functional equivalent packaged in tape and reel format instead of individual units.

FAQ

What are the supported output frequencies?

The device supports 62.5MHz, 125MHz, and 156.25MHz, selected via the N_SEL0 and N_SEL1 pins when using a 25MHz crystal.

How is the PLL bypassed?

Setting the PLL_ByPass pin to logic '1' enables the PLL bypass mode; setting it to '0' enables the PLL.

What is the recommended crystal specification?

Pericom recommends a 25MHz fundamental mode crystal with 18pF load capacitance, such as FL2500047 or FY2500091.
