MaxLinear Showcases Breakout Mode Clocking Support for 400 Gbps DR4 Optical Modules at ECOC 2018
ROME - Sept. 25, 2018 - 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 support for 400 Gbps breakout mode clocking in its MxL9354x products. The functionality will be on display at the company's stand (#684) at the European Conference on Optical Communication (ECOC) in Rome taking place from Sept. 24-26, 2018.
MaxLinear's Telluride 400 Gbps PAM4 DSP (MxL9354x), based on 100 Gbps single lambda technology, is enabling development of DR4 and FR4 optical modules for the upcoming hyperscale datacenter transition to 400 Gbps. The initial use case in this transition is expected to be dominated by use of 400 Gbps DR4 modules used in a breakout application.
The breakout mode of a 400 Gbps DR4 module requires certain clocking considerations that allow for the four 100 Gbps lanes to be treated as independent 100 Gbps ports and connect to a 100 Gbps DR1 or FR1 module on the other side. The unique clocking architecture of the MxL9354x makes it possible to achieve this requirement seamlessly.
The MxL9354x is a family of low-power, high-performance PAM4 DSP SoCs that enable 400 Gbps optical modules using a 4x100 Gbps optics interface. These SoCs are suitable for use within QSFP-DD, OSFP and COBO module form factors. Two options are currently available: the MxL93542 that integrates an EA-EML driver with 1.8V PP SE swing, and the MxL93543 that offers differential 800mV peak-to-peak swing for non EA-EML-based optics.
