8T49N1012-006NLGI8

Overview

The 8T49N1012-006NLGI8 is a programmable clock generator from the FemtoClock NG family. It features a single fractional-feedback PLL for frequency translation and jitter attenuation. The device supports up to four LVPECL, LVDS, HCSL, or LVCMOS outputs. Output frequencies range from 8kHz to 1.0GHz (differential) or 250MHz (LVCMOS). It accepts two differential input clocks and includes I2C register programming.

Feature Summary

• Generates multiple independent output frequencies from a single reference clock
• Supports hitless switching between input clocks with phase-slope limiting
• Integrates jitter attenuation and frequency synthesis capabilities

Applications

• SONET/SDH network line cards
• Ethernet network switches
• Wireless base station baseband units

Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm package type and pre-programming configuration. Confirm RoHS compliance status and lead-free packaging details directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when designing systems requiring low-jitter clock distribution with flexible output voltage levels. Ensure the application requires support for both differential and single-ended outputs within the specified frequency ranges.

Part Context

This part belongs to the 8T49N series of universal frequency translators. These devices utilize fourth-generation FemtoClock NG PLL technology to provide high-performance timing solutions for networking and telecommunications infrastructure applications.

Replacement Considerations

Consult official substitution guides for compatible alternatives such as the 8T49N242 series if higher output counts are required.
