8T49N1012-998NLGI8

Overview

The 8T49N1012-998NLGI8 is a 12-output frequency synthesizer from the FemtoClock NG series by Renesas Electronics. It supports high-speed data rates including 1G, 10G, 40G, and 100G SyncE, OTN, and SONET/SDH applications. The device operates with supply voltages of 2.375V to 2.625V and 3.135V to 3.465V. It features differential input and output capabilities with support for multiple input formats such as HCSL, LVCMOS, LVDS, LVHSTL, LVPECL, LVTTTL, and crystals. The component is housed in a surface-mount package and is currently designated as an End-of-Life product.

Feature Summary

Provides twelve independent clock outputs for complex system synchronization
Supports high-speed networking standards including 100G SyncE and OTN
Offers flexible input format compatibility for diverse source signals

Applications

100G Synchronous Ethernet (SyncE) networks
Optical Transport Network (OTN) systems
SONET/SDH infrastructure equipment

Procurement Notes

This component is officially classified as End-of-Life (EOL). Renesas Electronics has issued discontinuance notifications indicating that production will cease and the part will be phased out. Procurement should verify current availability through authorized distributors or consider alternative sourcing strategies due to the confirmed obsolescence status.

Selection Notes

Engineers selecting this part must account for its EOL status when designing new products. While it offers comprehensive output flexibility for high-speed telecom applications, long-term supply stability is not guaranteed. Design reviews should prioritize components with active lifecycle status to ensure manufacturing continuity and avoid future replacement risks.

Part Context

The 8T49N1012 belongs to the FemtoClock NG family, which specializes in low-jitter clock generation and distribution. This specific model provides twelve outputs, distinguishing it from lower-channel variants like the 8T49N241. It serves as a critical timing solution for telecommunications gear requiring precise synchronization across multiple network interfaces.
