8T49N105A-999NLGI8

Overview

The Renesas 8T49N105A-999NLGI8 is a FemtoClock NG Universal Frequency Translator and Synthesizer. It generates output frequencies from 0.98MHz to 312.5MHz, with most frequencies supported up to 1,300MHz. The device features a single differential input supporting LVPECL, LVDS, LVHSTL, and HCSL signals within an 8kHz to 710MHz range. It provides one programmable differential output pair (Q, nQ) configurable as LVDS or LVPECL. Power supply voltages for VCC, VCCA, and VCCO range from 2.375V to 3.465V. The component operates within an ambient temperature range of -40°C to 85°C.

Feature Summary

Universal Frequency Translator / Synthesizer with three operating modes: Frequency Synthesizer, High-Bandwidth Frequency Translator, and Low-Bandwidth Frequency Translator.
Single differential output pair (Q, nQ) programmable as LVDS or LVPECL interface levels.
Two factory-programmed default power-up configurations stored in One-Time Programmable (OTP) memory, selectable via CONFIG pin or I2C register.
Integrated alarm and monitoring functions including LOCK_IND, HOLDOVER, CLK_BAD, and XTAL_BAD status indicators.

Applications

Networking and communications applications requiring jitter attenuation.
PCI Express and computing systems utilizing high-bandwidth frequency translation.
General purpose clock generation from fundamental mode crystal inputs.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and lead-free status. Confirm that the device meets RoHS 6 compliance requirements for the intended assembly process. Check for any Product Change Notices (PCN) related to manufacturing site or material changes prior to procurement.

Selection Notes

Select this component when a single differential output is required with support for multiple input signaling standards including LVPECL, LVDS, LVHSTL, and HCSL. Ensure the design accommodates the 40-lead VFQFN package dimensions. Verify that the application requires either two distinct power-up configurations or dynamic reconfiguration via the I2C serial interface.

Part Context

This part belongs to the IDT8T49N105I FemtoClock NG family, which are low phase noise universal frequency translators. The series supports flexible clock generation for networking and computing environments. The device integrates delta-sigma fractional feedback division capabilities for precise frequency synthesis without strict crystal frequency requirements.

Replacement Considerations

Consult the official FemtoClock NG Ordering Guide for verified substitute part numbers within the same product family. Ensure replacement devices maintain compatibility with the 40-lead VFQFN footprint and electrical specifications.
