PI6LC48P0301LIEX

Overview

The PI6LC48P0301 is a 3-output LVPECL synthesizer from the HiFlex family, designed for Ethernet reference clock generation. It supports input frequencies of 19.53125MHz or 25MHz via crystal or single-ended LVCMOS/LVTTL reference. The device generates output frequencies including 125MHz, 156.25MHz, 312.5MHz, and 625MHz using proprietary low phase noise PLL technology. RMS phase jitter at 156.25MHz is typically 0.16ps (1.875MHz–20MHz) and 0.32ps (12kHz–20MHz). It operates on 2.5V or 3.3V supplies within an ambient temperature range of -40°C to +85°C.

Feature Summary

• Three differential LVPECL output pairs with selectable divider settings
• Supports 19.53125MHz or 25MHz crystal inputs or LVCMOS/LVTTL reference
• Ultra-low phase jitter: 0.16ps typical at 156.25MHz (1.875MHz–20MHz)
• Dual voltage operation: 2.5V or 3.3V supply modes

Applications

• Networking systems
• Ethernet interface circuits

Procurement Notes

Verify the ordering suffix against the datasheet table. The 'E' suffix indicates Pb-free and Green packaging. An 'X' suffix denotes tape and reel packaging. Confirm the package type is 24-TSSOP and ensure the specific variant matches the required commercial or industrial temperature rating.

Selection Notes

Select based on required output frequency and divider settings defined in the Bank A and Bank B frequency tables. Ensure the input source matches either the crystal oscillator interface or the Ref_IN pin configuration. Verify power supply requirements align with the 2.5V or 3.3V operational modes specified in the DC characteristics.
