PI6LC48P03AZHIE

Overview

The PI6LC48P03AZHIE is a 3-output LVPECL synthesizer from the HiFlex family, designed for Ethernet reference clock generation. It supports output frequencies of 125MHz, 156.25MHz, 312.5MHz, and 625MHz using 31.25MHz or 26.041666MHz crystals. The device achieves an RMS phase jitter of 0.3ps (typical) at 156.25MHz within the 12kHz–20MHz bandwidth. It operates on full 3.3V or 2.5V supply modes and features selectable crystal or single-ended LVCMOS/LVTTL inputs. Packaged in a lead-free 28-TQFN, it functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Three differential LVPECL output pairs with selectable divider settings
• Ultra-low phase jitter: 0.3ps typical RMS at 156.25MHz (12kHz–20MHz)
• Supports 31.25MHz or 26.041666MHz crystal inputs or LVCMOS/LVTTL reference
• Dual voltage operation: 3.3V ±5% or 2.5V ±5%

Applications

• Networking systems requiring Ethernet reference clocks
• High-speed data interface synchronization
• Industrial embedded timing solutions

Procurement Notes

Verify the ordering suffix 'ZHIE' confirms the 28-pin TQFN package and tape-and-reel packaging format. Ensure compatibility with the specified industrial temperature range (-40°C to +85°C). Confirm RoHS compliance and green material status as indicated by the 'E' suffix designation in the manufacturer's ordering guide.

Selection Notes

Select this component when three independent LVPECL outputs are required for Ethernet applications. Verify that the system can accommodate either a 31.25MHz or 26.041666MHz parallel resonant crystal with 18pF load capacitance. Ensure power supply filtering meets the datasheet recommendations for VDDA isolation to maintain specified jitter performance.

Part Context

This part belongs to the Pericom HiFlex family of high-performance clock solutions, now manufactured under Diodes Incorporated. It is specifically optimized for generating precise Ethernet reference frequencies using proprietary low phase noise PLL technology. The device integrates separate power domains for core, analog, and output sections to minimize noise coupling.

Replacement Considerations

Check for pin-compatible alternatives within the same HiFlex family, such as the PI6LC48P0201 series, if fewer outputs are sufficient. Verify that substitute devices support the same 28-TQFN footprint and industrial temperature ratings.
