The GX74470 is a very low-power, high-performance, quad-channel linear driver, designed for 200G/400G optical transmitters for metro applications.

The GX74470 is a small form factor (SFF) packaged surface mount device (SMD) with differential inputs and single-ended outputs consisting of 4 x 46Gbps broadband amplifier channels, each capable of driving a linear output voltage of 4.5Vpp, suitable for multi-level modulation applications. 


  • Data rate up to 46Gbps per channel for 200G/400G DP-mQAM applications
  • 10dB dynamic range of gain control
  • 1.3W (typical) per channel at linear 4.5Vpp
  • Ultra-low inter-channel cross-talk
  • Small form factor SMD
  • Internal high-frequency chokes to supplies
  • Internally DC-blocked RF inputs and outputs
  • Peak detector
