概要

The GX76474 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 GX76474 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 60Ω differential interface with an open collector type output stage, and linear output voltage of 4.0Vppd suitable for Silicon Photonics modulator and multi-level modulations.
