8T49N105A-003NLGI8

Overview

The Renesas 8T49N105A-003NLGI8 is a FemtoClock NG Universal Frequency Translator in a 40-lead VFQFN package. It generates output frequencies from 0.98MHz to 1,300MHz using a single differential input (LVPECL, LVDS, LVHSTL, HCSL) or crystal source. The device supports three modes: frequency synthesizer, high-bandwidth translator, and low-bandwidth translator with jitter attenuation. It features two factory-programmed OTP configurations selectable via the CONFIG pin or I2C register. Outputs are programmable as LVDS or LVPECL.

Feature Summary

Single differential input supporting LVPECL, LVDS, LVHSTL, and HCSL levels
Two factory-programmable default power-up configurations stored in OTP memory
Low RMS phase jitter of 439fs typical at 155.52MHz (12kHz-20MHz offset)
I2C serial interface for post-power-up register reconfiguration

Applications

PCI Express networking and computing systems
General purpose clock translation
Networking and communications equipment requiring jitter attenuation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm exact factory-programmed parameters. Confirm package availability and lead times through authorized distributors. Check for product change notices regarding assembly sites or material updates.

Selection Notes

Select this component when a single-output universal frequency translator with flexible input/output voltage options is required. Ensure the desired output frequency falls within the supported divider ranges defined in the datasheet. Verify that the required loop bandwidth settings align with the application's jitter tolerance and reference tracking needs.

Part Context

This part belongs to the IDT8T49N105I FemtoClock NG family. It is designed as a general-purpose low phase noise translator suitable for demanding networking applications. The device integrates alarm monitoring functions and supports both integer and fractional feedback division for precise frequency generation.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Ensure any replacement maintains the 40-lead VFQFN footprint and compatible supply voltage ranges.
