MaxLinear Launches the MxL9244 45Gbaud Linear Mach-Zehnder Modulator Driver for 200Gbps / 400Gbps Telecom and Data Center Applications

  • MxL9244’s frequency response, best-in-class linearity and low power make it the ideal optical modular driver for 45Gbaud transceiver designs; Transceiver design performance is optimized when used with 45Gbaud MxL9142 transimpedance amplifier in an intradyne coherent receiver

MaxLinear Inc. (NYSE: MXL), a leading provider of radio frequency (RF) and mixed-signal integrated circuits for the connected home and wired and wireless infrastructure markets, today announced the MxL9244, a quad-channel linear Mach-Zehnder (MZ) modulator driver for next-generation 200Gbps / 400Gbps coherent systems.

The MxL9244 is designed for data center, long-haul and metro telecom network systems. With its best-in-class total harmonic distortion (THD) performance, the MxL9244 supports next-generation linear DP-QPSK / DP-16QAM / DP-32QAM coherent transceiver designs where component linearity and bandwidth performance is critical for optimal optical signal-to-noise ratio (OSNR) performance.

The MxL9244 features a serial peripheral interface (SPI) to perform all control and monitoring functions, which greatly simplifies module peripheral circuitry design. A programmable input gain equalizer compensates for high frequency loss from the printed circuit board (PCB) and the package. The MxL9244 can support up to 400Gbps data rate in a single wavelength when used with higher-level modulation such as DP-32QAM.

The device also integrates broadband bias tee to maintain optimal power dissipation. The MxL9244 is available in a small, 14mm x 9mm, SMT package that makes it ideal for the next-generation CFP-DCO, CFP2-ACO or smaller form-factor module designs where high face-plate density and minimized power dissipation are desired.

“A 45Gbaud coherent solution is appealing to both datacenter and telecom operators as it not only offers longer reach capability for 200Gbps and higher long-haul transport, but also enables 400Gbps data transport in a single wavelength,” said Bird Yuan, MaxLinear Director of Marketing for High Speed Interconnect Products. “We expect that the MxL9244’s leading optical modulator driver performance – combined with the companion MxL9142 TIA –  will have a significant impact on the performance of emerging 200Gbps / 400Gbps products.”


The MxL9244 samples will be available beginning in Q2 2017. More information is available at
