8T49N006A-000NLGI8

Overview

The 8T49N006A-000NLGI8 is a programmable clock generator from the FemtoClock NG series by Renesas Electronics. It features four selectable LVPECL or LVDS outputs and utilizes fourth-generation PLL technology for low RMS phase jitter. The device accepts differential inputs such as LVPECL, LVDS, or HCSL and operates on a full 2.5V or 3.3V power supply. Configuration is managed via an I²C interface, supporting operation across a -40°C to 85°C ambient temperature range.

Feature Summary

• Generates multiple output frequencies from a single reference clock using fractional-feedback PLL technology
• Provides selectable LVPECL or LVDS output levels for flexible system integration
• Supports I²C programming for register configuration and frequency selection

Applications

• High-speed networking equipment requiring precise clock distribution
• Telecommunications infrastructure utilizing SONET/SDH standards
• Test and measurement instruments demanding low jitter performance

Procurement Notes

Verify the specific ordering suffix against the official Renesas datasheet to confirm pinout and electrical characteristics. Confirm package availability and lead times directly with authorized distributors. Ensure compliance with RoHS directives and check for any recent product change notices affecting manufacturing sites.

Selection Notes

Select this component when low phase jitter and flexible output voltage levels are required. Compare input/output ratios and operating voltage ranges against system requirements. Verify that the I²C interface compatibility matches the host controller design constraints.

Part Context

This part belongs to the FemtoClock NG family of ultra-low jitter clock generators. It shares architectural similarities with other members like the 8T49N004I and 8T49N008I, differing primarily in output count and specific factory-programmed frequency configurations.

Replacement Considerations

Check for direct substitutes within the 8T49N00x series. Verify pin-to-pin compatibility and electrical parameter equivalence before substitution.
