GX76473 - Block Diagram
Description
The GX76473 is a low-power, high-performance, quad-channel linear driver chip that is designed for 400G/600G optical integrated transmitter small-form factor (SFF) modules for metro and long-haul applications.
The GX76473 integrated quad lanes of driver with SPI circuitry for DC controls on a single die. Each channel of driver has 100Ω differential AC-coupled input and 100Ω differential DC-coupled output, and linear output voltage of 1.8Vppd suitable for InP multi-level modulations.
