MaxLinear's MxL9101 28Gbps TIA Optimized for Low-Power 100Gbps Optical Transceivers

MaxLinear Inc., 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 MxL9101 28Gbps transimpedance amplifier (TIA) array optimized for low-power 100Gbps optical transceivers.

The MxL9101 is a high dynamic range, four-channel 28Gbps TIA that is designed for use in receive modules of 100Gbps Ethernet optical transceivers. The device features best-in-industry sensitivity and overload for robust signal reception in SR4/PSM4/CLR4/LR4 applications. When combined with an avalanche photodiode (APD), the receiver can also support ER4-lite applications. The TIA features the industry’s lowest power dissipation of 0.32W and adjustable bandwidth control.

All of these features make the part ideal for small form-factor pluggable transceivers including CFP, CFP2, CFP4 and QSFP28 form factors.

“The 100Gigabit per second transceiver market is in the first inning of a several million unit rollout. So, optical module designers are imposing extremely tight constraints on the power consumption of the transceiver components, and are demanding very high sensitivity performance, especially in small form-factor products such as QSFP28 pluggable targeting data centers,” said Brendan Walsh, MaxLinear’s Vice President of Marketing for Infrastructure Products. “The MxL9101 addresses these customer needs perfectly and expands our 100G+ product portfolio to offer transceiver manufacturers a complete TIA solution for high-speed networks.”

Technical Highlights

The MxL9101 features:

  • 0.32W typical power consumption
  • Best-in-class dynamic range
  • Bandwidth control
  • > 45dB CH-CH isolation
  • Photodiode bias
  • Receiver signal strength indicator (RSSI)
  • Die size of 3.2mm x 1.6mm
