Overview

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.

Features

  • Data rate up to 64Gbps per channel for 400G/600G DP-mQAM applications
  • > 40GHz bandwidth
  • > 10dB dynamic range of gain control
  • < 2.0W (typical) at linear 2.0Vppd
  • AC-coupled 100Ω differential input/DC-coupled 55Ω differential 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
