GX76470 - Block Diagram
Description
The GX76470 is a low-power, high-performance, quad-channel linear driver chip. It is designed for 400G/600G optical integrated transmitter small form factor (SFF) modules for metro and long-haul applications.
The GX76470 integrates the quad lanes of the driver with SPI circuitry for DC controls on a single die. Each channel of the driver has 100Ω differential AC-coupled input and 55Ω differential DC-coupled output, and a linear output voltage of 2.8Vppd suitable for InP multi-level modulations.
