GX78472-DNT

Overview

The GX78472-DNT is a quad-channel linear driver integrated circuit designed for high-speed optical communication applications. It features four differential output channels capable of supporting data rates up to 128 GBaud per lane, enabling aggregate throughput of 800 Gbps and beyond in advanced multi-level QAM modulation systems. The device integrates SPI circuitry for DC control functions on a single die, providing precise management of channel parameters. Designed for metro and long-haul optical modules, it supports complex signal processing requirements for next-generation coherent optical transceivers.

Feature Summary

Quad-channel architecture with differential outputs optimized for 800Gbps and higher speed optical modules
Integrated SPI interface for direct digital control of DC operating parameters
Supports advanced multi-level QAM modulation schemes for high spectral efficiency
Single-die integration combining driver functionality with control logic

Applications

800G and beyond optical transceiver modules
Metro and long-haul coherent optical communication systems
Advanced multi-level QAM modulation platforms

Part Context

The GX78472 belongs to Renesas' portfolio of optical modulator drivers, specifically engineered for high-bandwidth data center and telecommunications infrastructure. It complements other devices like the GX76471 by offering higher channel speeds (128 GBaud) suitable for evolving 800G+ standards. This component addresses the need for compact, high-performance solutions in dense optical packaging environments.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in verified documentation. Designers should consult Renesas official resources for current equivalent recommendations or updated product line replacements.
