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. 

Features

  •  Data rate up to 64Gbps per channel for 400G/600G DP-mQAM applications
  • > 40GHz Bandwidth
  • > 10dB dynamic range of gain control
  • 2.4W (typical) at linear 4.0Vppd
  • AC-coupled 100Ω differential input/ open collector configuration at the output
  • Ultra-low inter-channel cross-talk
  • Peaking adjustment functionality 
  • Analog control for gain and output voltage setting, and analog monitor for peak detector and gain control monitor
  • OIF compliant SPI digital interface integration
