PI6LC48P0301LIE

Overview

The PI6LC48P0301LIE is a 3-output LVPECL synthesizer from Diodes Incorporated’s HiFlex family, designed for Ethernet reference clock generation. It supports input frequencies of 19.53125MHz or 25MHz via crystal or LVCMOS/LVTTL single-ended inputs. The device generates output frequencies including 125MHz, 156.25MHz, 312.5MHz, and 625MHz using proprietary low phase noise PLL technology. It operates on full 3.3V or 2.5V supply modes within an industrial ambient temperature range of -40°C to +85°C. The component is housed in a lead-free 24-TSSOP package.

Feature Summary

• Three differential LVPECL output pairs with selectable divider settings
• Ultra-low RMS phase jitter: 0.16ps typical at 156.25MHz (1.875MHz–20MHz bandwidth)
• Flexible input interface supporting crystal oscillator or LVCMOS/LVTTL single-ended clock
• Supports standard Ethernet frequencies: 125MHz, 156.25MHz, 312.5MHz, and 625MHz

Applications

• Networking systems
• Ethernet interface circuits

Procurement Notes

Verify the ordering suffix 'I' confirms the Industrial temperature grade (-40°C to +85°C). Confirm the 'E' suffix indicates Pb-free and Green packaging status. Ensure the specific tape and reel quantity matches project requirements if an 'X' suffix is added to the base part number.

Selection Notes

Select this component when low phase jitter is critical for Ethernet applications. Ensure power supply filtering includes separate VDD, VDDA, and VDDO connections with appropriate bypass capacitors to isolate switching noise. Verify that the system requires LVPECL outputs and can accommodate the 24-TSSOP footprint.

Part Context

This part belongs to the Pericom HiFlex family of high-performance clock solutions manufactured by Diodes Incorporated. It is specifically optimized for generating precise clock signals required by modern networking equipment and Ethernet interfaces.

Replacement Considerations

Check datasheets for other PI6LC48 series variants to confirm pin compatibility and electrical specifications before substitution.
