PI6LC48P0301AZHE

Overview

The PI6LC48P0301A is a 3-output LVPECL synthesizer optimized for Ethernet reference clock generation. It supports output frequencies of 125MHz, 156.25MHz, 312.5MHz, and 625MHz using a 25MHz crystal or single-ended input. RMS phase jitter at 156.25MHz is typically 0.26ps (max 0.4ps) in the 12kHz–20MHz range. The device operates on full 3.3V or 2.5V supplies and is available in a lead-free 28-TQFN package.

Feature Summary

• Three differential LVPECL output pairs with selectable divider settings
• Supports 125MHz, 156.25MHz, 312.5MHz, and 625MHz outputs
• Ultra-low phase jitter: 0.26ps typical at 156.25MHz (12kHz–20MHz)
• Compatible with 25MHz crystals or LVCMOS/LVTTL single-ended inputs

Applications

• Networking systems
• Ethernet interface clocking

Procurement Notes

Verify the ordering suffix to confirm packaging and temperature grade. 'ZHE' indicates a commercial grade 28-pin TQFN package. Adding an 'X' suffix denotes tape and reel packaging. Ensure the specific variant matches the required ambient operating temperature range.

Selection Notes

Select based on required output frequency and divider settings via NA_SEL and NB_SEL pins. Verify power supply compatibility (3.3V or 2.5V). For crystal-based designs, use 18pF parallel resonant crystals. Ensure proper power supply filtering with 0.1μF bypass capacitors and isolation resistors for optimal jitter performance.

Part Context
