8T49N105A-007NLGI

Overview

The IDT8T49N105I is a FemtoClock NG Universal Frequency Translator and Synthesizer featuring fourth-generation technology. It generates output frequencies from 0.98MHz to 1300MHz using a single differential input (LVPECL, LVDS, LVHSTL, HCSL) or a 16MHz-40MHz crystal. The device supports three modes: Frequency Synthesizer, High-Bandwidth Translator, and Low-Bandwidth Translator with jitter attenuation. It provides one programmable LVPECL or LVDS differential output pair. Key electrical parameters include an input frequency range of 8kHz-710MHz, supply voltages of 2.5V or 3.3V, and operation from -40°C to 85°C. RMS phase jitter is typically 439fs at 155.52MHz and 285fs at 400MHz.

Feature Summary

Single differential output configurable as LVPECL or LVDS
Three operating modes: Frequency Synthesizer, High-Bandwidth Translator, Low-Bandwidth Translator
Two factory-programmable power-up configurations stored in OTP memory
I2C serial interface for register programming and post-power-up reconfiguration

Applications

Networking and communications line cards
PCI Express and computing systems
General purpose clock translation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the selected variant matches the required voltage levels and pinout configuration.

Selection Notes

Select this component when a single differential output is sufficient for the design. Choose between LVPECL and LVDS based on the receiving device's input requirements. Utilize the two factory-programmed configurations if distinct hardware setups are needed without I2C intervention. Verify that the desired output frequency falls within the supported divider ranges defined in the datasheet.

Part Context

This device belongs to the IDT8T49N105I family within the FemtoClock NG series. It serves as a general-purpose low phase noise frequency translator suitable for applications requiring flexible clock generation from various reference sources.

Replacement Considerations

Consult the manufacturer's official obsolescence notices and cross-reference guides for verified replacement part numbers. Ensure any substitute device maintains compatibility with the existing I2C address and register map if software migration is not planned.
