  • New MxL9154 and MxL9124 transimpedance amplifiers join DSP SoCs to provide a complete solution for 400Gbps PAM4 network equipment for intra-data center applications

CARLSBAD, Calif.--(BUSINESS WIRE)-- MaxLinear, Inc. (NYSE:MXL), a leading provider of radio frequency (RF), analog and mixed-signal integrated circuits for the connected home, wired and wireless infrastructure, and industrial and multimarket applications, today announced the MxL9154 and MxL9124 quad transimpedance amplifiers (TIA) as new members of its Telluride family of components for linear PAM4 400Gbps network systems.

Telluride products enable system vendors to develop a 400Gbps optical interconnect module in a compact form factor for intra-datacenter applications. MaxLinear has already launched the first Telluride products, the MxL935XX family of DSP SoCs with integrated electro-absorption modulated laser (EA-EML) drivers. The MxL935XX products are the industry's first 400Gbps DSP SoC using the 100G per wavelength technology.

The MxL9154 offers extremely low input referred noise performance of 11pA/sqrt(Hz) while consuming very low power of 200mW/channel. The device offers a bandwidth of >25GHz including the photodiode (PD) and satisfies the stringent 53Gbaud PAM4 requirements by achieving 3 percent linearity up to overload conditions. The TIA also offers receive signal strength indicator (RSSI) outputs for all four channels. The MxL9154 is an ideal complement to the MxL9354X PAM4 DSP SoCs, which when shipped together deliver best-in-class performance for both power and cost.

The MxL9124 TIA offers the same functionality in a lower bandwidth option that is suitable for 50Gbps PAM4 applications. The TIAs can be paired with PIN PDs or an externally biased avalanche photodiode (APD) to achieve different performance and reach requirements. Together, the MxL9154 and MxL9124 deliver the bandwidth and noise performance for a range of applications including 200Gbps DR4, 200Gbps FR4, 200Gbps LR4, 400Gbps DR4, 400GbpsFR4 and 400Gbps LR8.

“PAM4-based 100Gbps wavelength technology is emerging as the best option for 400Gbps networks for intra datacenter applications. At these higher data rates, it is extremely important that all high-speed components be designed and optimized together to offer the best overall performance,” said Will Torgerson, MaxLinear Vice President & General Manager. “The MxL9154 and MxL9124 TIAs have been developed in conjunction with the MxL9354X PAM4 DSP SoC for seamless optimization between the components.”

The MxL9154 features an I2C interface that facilitates control of its performance directly from the MxL9354X PAM4 DSP SoC. With a die size of 3.2mm x 1.6mm, the TIA fits into quad-ROSA size restrictions required for the QSFP-DD and OSFP module form factors.
