The GX79472 is a low-power, high-performance, quad-channel linear driver chip that is designed for 800G and beyond optical integrated transmitter small form factor (SFF) modules for metro and long-haul applications.
The GX79472 integrates the quad lanes of the driver with SPI circuitry for DC controls on a single die. Each channel of the driver has a 100Ω differential AC-coupled input and a single-ended output with a back-terminated output stage. The output stage allows for an external AC-coupled interface with optical modulators having a wide characteristic impedance range from 30Ω to 50Ω. The linear output voltage of 2.0Vpps is suitable for the lithium niobate (LiNbO3) optical modulators with multi-level modulations.
