MaxLinear Introduces MxL9162 64Gbaud Linear Transimpedance Amplifier for Next-Generation 400Gbps / 600Gbps Coherent Systems

  • The MxL9162 TIA enables next-generation 400Gbps / 600Gbps coherent long-haul, metro and data-center interconnect receiver designs with industry-leading RF performance, advanced features and low power dissipation

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 introduced the MxL9162, a 64Gbaud linear coherent transimpedance amplifier (TIA) for next-generation 400Gbps/600Gbps dense wave division multiplexing (DWDM) coherent systems.

The MxL9162 features best-in-class RF system performance including over 40GHz channel bandwidth, low total harmonic distortion (THD), input referred noise density, power dissipation and channel crosstalk. The device exceeds the high-performance requirements of next-generation 64Gbaud high bandwidth (HB) micro-intradyne coherent receiver (ICR) designs for long-haul, metro and datacenter interconnect applications.

The MxL9162 is a dual-channel TIA with a per-channel data rate of 64Gbaud. Its excellent THD and optimal channel signal-to-noise-ratio enable a higher order of signal modulation such as 64-QAM that is required to support 400Gbps/600Gbps single wavelength data rates. An integrated photo detector bias and SPI interface with integrated high-resolution DAC/ADC greatly simplifies the peripheral circuit design, reduces module bill-of-material cost and minimizes substrate real estate. Ultra-low input referred noise density and low power consumption make it the best option for next-generation HB micro-ICR designs.

Additionally, the integrated equalizer function with programmable gain peaking profile allows receiver sensitivity to be optimized with PDs and package designs from a wide range of manufacturers. The MxL9162 also supports the low differential output swings required for the next generation of low-power coherent DSPs.

MaxLinear will demonstrate the MxL9162 64Gbaud coherent TIA at OFC 2017 which will take place at the Los Angeles Convention Center on March 21 to 23, 2017.  The company will be in stand #2471.

“Today, mainstream 32Gbaud-based 100Gbps/200Gbps DWDM coherent systems bring a great balance of performance and cost to optical networks. For telecom and data center operators to further increase data capacity, and to reduce cost-per-bit, coherent technology supporting higher bandwidth and a higher order of modulation is required,” said Bird Yuan, MaxLinear Director of Marketing, High Speed Interconnects. “We believe MaxLinear’s high-speed interconnect component technology delivers the best performance and enables next-generation high bandwidth coherent deployments.”


The MxL9162 will begin sampling in the second quarter of 2017. More information is available at
