Overview
The GX76472-DNT is a low-power, high-performance quad-channel linear driver chip designed for 400G/600G optical integrated transmitter small form factor (SFF) modules used in metro and long-haul applications. It integrates four driver lanes with SPI circuitry for DC controls on a single die. Each channel features a 100Ω differential AC-coupled input and a 55Ω differential DC-coupled output, providing a linear output voltage of 2.8Vppd suitable for InP multi-level modulations.
Feature Summary
- Integrates four independent linear driver channels with dedicated SPI control circuitry on a single die
- Provides differential AC-coupled inputs and differential DC-coupled outputs for signal integrity
- Delivers linear output voltage optimized for InP multi-level modulation schemes
Applications
- 400G/600G optical integrated transmitter small form factor (SFF) modules
- Metro network transmission systems
- Long-haul optical communication links
Procurement Notes
Verify the specific suffix -DNT indicates wafer-level packaging when sourcing. Confirm availability through authorized distributors as inventory levels fluctuate. Ensure compatibility with existing SFF module designs requiring 2.8Vppd differential drive capabilities for InP modulators.
Selection Notes
Select this component for applications requiring low power consumption and high performance in dense optical transceivers. The integration of SPI controls simplifies system design by reducing external component count. Verify that the 55Ω differential DC-coupled output impedance matches the target modulator requirements.
Part Context
This device belongs to Renesas' portfolio of optical driver solutions targeting high-speed data center and telecommunications infrastructure. It complements other drivers like the GX76474, which offers higher voltage swing for silicon photonics, while this model focuses on InP-based multi-level modulation applications.
Replacement Considerations
The GX76471 serves as a direct functional equivalent within the same product family. Both devices share identical electrical characteristics, including the 2.8Vppd output voltage and 55Ω differential DC-coupled output interface.
