PI6LC48P03LE

Overview

The PI6LC48P03LE 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 features ultra-low phase jitter (0.3ps typical at 156.25MHz) and operates on full 3.3V or 2.5V supplies. It accepts crystal or LVCMOS/LVTTL inputs and provides three differential LVPECL outputs in a 24-TSSOP package.

Feature Summary

• Three differential LVPECL output pairs with selectable divider settings
• Ultra-low RMS phase jitter of 0.3ps typical at 156.25MHz (12kHz–20MHz)
• Supports 3.3V ±5% or 2.5V ±5% supply modes
• Selectable crystal oscillator interface or single-ended LVCMOS/LVTTL input

Applications

• Networking systems
• Ethernet interface applications

Procurement Notes

Verify the 'L' suffix indicates Pb-free and Green packaging and the 'E' suffix denotes tape and reel format. Confirm the operating temperature range matches commercial specifications (-40°C to +85°C). Ensure power supply filtering techniques are applied to achieve optimum jitter performance.

Selection Notes

Select based on required output frequency (125MHz, 156.25MHz, 312.5MHz, or 625MHz) and supply voltage (3.3V or 2.5V). Use the frequency select pins (NA_SEL, NB_SEL, FBN) to configure outputs. For crystal inputs, use 18pF parallel resonant crystals (31.25MHz or 26.041666MHz).

Part Context

The PI6LC48P03LE belongs to Pericom’s HiFlex family of high-performance clock solutions. It utilizes proprietary low phase noise PLL technology to generate precise Ethernet reference clocks. The component is manufactured by Diodes Incorporated, which acquired Pericom Semiconductor Corporation.
