PI6LC48P0101LIEX

Overview

The PI6LC48P0101LIEX is a 2-output LVDS synthesizer from the HiFlex family, designed for Ethernet reference clock generation. It supports output frequencies of 62.5MHz, 125MHz, and 156.25MHz using a 25MHz crystal or single-ended input. The device features ultra-low phase jitter, with typical RMS values of 0.2ps (1.875MHz–20MHz) and 0.32ps (12kHz–20MHz) at 156.25MHz. It operates on full 3.3V or 2.5V supply modes and is available in a lead-free 20-TSSOP package.

Procurement Notes

Verify the ordering suffix 'X' indicates tape and reel packaging. Confirm the 'L' suffix denotes Pb-free and Green compliance. Ensure the specific temperature grade matches the design requirements, as commercial and industrial variants exist within this part number family.

Selection Notes

Select based on required output frequency settings via N_SEL pins. Verify power supply compatibility for either 3.3V or 2.5V operation. Consider thermal resistance characteristics if operating in still air environments. Ensure proper power supply filtering techniques are implemented to maintain optimal jitter performance.
