MaxLinear Introduces MxL9103, a 28Gbaud Linear TIA For 100Gbps/400Gbps Fiber-Optic Data Center Applications

  • The MxL9103 TIA Offers Lowest Power Consumption And Best Performance For 100Gbps+ Data Center Optical Transceiver Designs

MaxLinear Inc. (NYSE: MXL), a leading provider of radio frequency (RF) and mixed-signal integrated circuits for cable and satellite broadband communications, the connected home, and for data center, metro, and long-haul fiber networks, announced the MxL9103, a single-channel 28Gbps linear transimpedance amplifier (TIA) targeting low-power pulse-amplitude modulation (PAM-4) and discrete multi-tone (DMT) optical transceivers for data center transceiver designs

The MxL9103 features best-in-class power consumption of 140mW, which makes it ideally suited for power-sensitive data center designs. The excellent total harmonic distortion (THD) performance and ultra-wide bandwidth supports the linearity required for higher-order-modulation of PAM-4 and DMT, which enables either 50Gbps or 100Gbps data rates on a single lambda (wavelength). The high dynamic range of the IC ensures the best signal reception quality.

The MxL9103 provides automatic-gain-control function for simplified interface design and system control scheme between the TIA and the digital signal processor (DSP). It also integrates received-signal-strength-indicator (RSSI), output shutdown, bandwidth control and photodetector bias voltage functions on-chip.

The TIA is well suited for SFP28 low-power optical transceiver module designs.

“Low power consumption and support of advanced modulation schemes make the MxL9103 optimal for next-generation, low-cost data center transceivers,” said Brendan Walsh, MaxLinear’s Vice President of Marketing for Infrastructure Products. “This device expands our high-speed optical interconnect product family, making MaxLinear a one-stop solution vendor for 100Gbps+ transceiver designs.”

Technical Highlights

The MxL9103 features:

  • 140mW typical power consumption
  • Typical 3% total harmonic distortion (THD)
  • Best-in-class dynamic range
  • Photodetector bias
  • Bandwidth control
  • Receiver signal strength indicator (RSSI)
