MaxLinear Launches Wide Bandwidth Linear 56Gbps TIA for PAM-4 & DMT based 100Gbps / 400Gbps Data Center Networks

  • High-Throughput and Support for PAM-4 and DMT Modulation Schemes Help Reduce Cost and Power Draw for 100Gbps & 400Gbps Optical Networking Systems

LOS ANGELES — (BUSINESS WIRE) — March 24, 2015 — MaxLinear Inc. (NYSE: MXL), a leading provider of integrated radio frequency (RF) and mixed-signal integrated circuits for broadband communications applications, today announced the MxL9103, a 56Gbps wide bandwidth linear trans-impedance amplifier (TIA) for 100Gbps / 400Gbps fiber-optic data center networks based on PAM-4 & DMT modulation schemes.

The MxL9103 is a single-channel wide-bandwidth linear TIA that supports four level pulse-amplitude modulation (PAM-4) based implementations of emerging 100Gbps and 400Gbps optical networking systems in modern data centers. In addition to PAM-4 applications, the IC can also be used for discrete multi-tone modulation (DMT) applications utilized in long haul, and metro optical transport systems. The device also integrates automatic gain control (AGC) and received-signal-strength-indicator (RSSI) functions, which greatly simplify the design of such complex networking systems.

The high throughput and linearity of the MxL9103 TIA enables module manufacturers to reduce costly optical and electrical components in their designs, thereby lowering cost and energy consumption.

For example, a complete 100Gbps receive optical sub-assembly (ROSA) can be developed using just two MxL9103 TIAs, two photo diodes, and the associated optical demux/filter. This represents a significant cost and power saving relative to four 28Gbps TIAs, 4 photo diodes, and associated demux/filters required in conventional NRZ modulation-based implementation 100Gbps systems.

The new MxL9103 will be on display at OFC 2015 (March 24-26; booth 1968).

“Higher-order modulation format is a critical element of next-generation 100G and 400G modules for the data center because the emphasis is on reducing power consumption, size and cost,” said Will Torgerson, Global Sales Vice President for MaxLinear. “With support for PAM-4 and DMT - with margin - the MxL9103 is an ideal solution for these equipment manufacturers.”


The MxL9103 is sampling in April, with general availability planned for September 2015. For more product information, contact MaxLinear sales team at
