8T49N105A-000NLGI8

Overview

The Renesas Electronics 8T49N105A-000NLGI8 is a FemtoClock NG Universal Frequency Translator and Synthesizer. It generates output frequencies from 0.98MHz to 1300MHz using an input range of 8kHz to 710MHz or a 16MHz-40MHz crystal. The device features two factory-programmable configurations selectable via the CONFIG pin or I2C register, supporting LVPECL or LVDS differential outputs. It operates on 2.5V or 3.3V supplies within a -40°C to 85°C temperature range in a 40-VFQFN package.

Feature Summary

Universal Frequency Translator with three modes: Frequency Synthesizer, High-Bandwidth Translator, and Low-Bandwidth Translator.
Dual factory-programmed default configurations stored in OTP memory for power-up selection.
Single differential output pair (Q, nQ) programmable as LVPECL or LVDS.
I2C serial interface for post-power-up register reconfiguration.

Applications

Networking and communications line cards requiring specific clock translation ratios.
PCI Express and computing systems utilizing high-bandwidth frequency translation.
General purpose applications requiring jitter attenuation via low-bandwidth mode.

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance status and check for End-of-Life notifications or Product Change Notices prior to procurement. Ensure supply chain stability as availability may vary.

Selection Notes

Select this model for applications requiring flexible frequency synthesis from diverse input sources. Choose based on required output voltage levels (LVPECL/LVDS) and whether dual configuration support is needed. Verify that the target frequency falls within the supported divider ranges defined in the datasheet.

Part Context

This component belongs to the IDT8T49N105I FemtoClock NG series. It serves as a general-purpose clock generator suitable for replacing legacy fixed-frequency oscillators in complex digital systems requiring precise frequency translation.

Replacement Considerations

Direct replacements require matching the 40-VFQFN package and electrical specifications. Consult manufacturer documentation for updated part numbers if the original series is discontinued.
