描述

The GX76476 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 GX76476 integrates the quad lanes of the driver with SPI circuitry for DC controls on a single die. Each channel of the driver has a 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.

特性

  • Data rate up to 64Gbps per channel for 400G/600G DP-mQAM applications
  • >65GHz bandwidth
  • >10dB dynamic range of gain control
  • 2.7W (typical) at linear 4.0Vppd
  • AC-coupled 100Ω differential input/open-collector configuration at the output
  • Ultra-low inter-channel crosstalk
  • Peaking adjustment functionality
  • Analog control for gain and output voltage setting, and analog monitor for peak detector and gain control monitor
  • Optical Internetworking Forum (OIF)-compliant SPI digital interface integration
