GX76471 - Block Diagram
描述
The GX76471 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 GX76471 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.
