The MxL9234 is a 32Gbd quad linear/limiting optical modulator driver that supports 100Gbps, 200Gbps, or 400Gbps coherent transmission systems.

The MxL9234 has differential inputs and differential outputs, and is housed in a 14mm x 9.1mm x 2.1mm surface mount package. The device includes four channels of high-performance wideband amplifiers with programmable input equalization function, analog or digital (SPI) controls, MGC or AGC, and integrated broadband bias tees.

In addition to best-in-class core RF performance (excellent linearity, high bandwidth, and lowest output jitter) the ultra-low power dissipation makes it ideal for 100G/200G CFP2-ACO and CFP-DCO transceiver design for datacenter interconnect (DCI) and metro applications.

The MxL9234 is lead-free and RoHS-compliant.

  • Low-power dissipation (2.2W @ 4Vppd Vout)
  • Excellent linearity (THD = 2% @ 4Vppd Vout)
  • Low additive jitter @ 500fs
  • Up to 4Vppd output swing in linear mode
  • Up to 5Vppd output swing in limiting mode
  • Programmable input gain equalization
  • Analog or SPI digital control/monitor mode
  • AGC/MGC control mode select
  • Differential input and differential output
  • Integrated temperature sensor
  • Integrated broadband bias tees

  • 200Gbps linear CFP2-ACO/CFP-DCO transceiver for metro/DCI applications
  • 100Gbps linear/limiting CFP2-ACO/CFP-DCO transceiver for long-haul/metro/DCI applications
