In booth #1A32 at the China International Optoelectronic Exposition (CIOE 2018) in Shenzhen, China (5–8 September) and in booth #579 at the European Conference on Optical Communication (ECOC 2018) in Rome, Italy (24–26 September), MACOM Technology Solutions Holdings Inc of Lowell, MA, USA (which makes semiconductors, components and subassemblies for RF, microwave, millimeter-wave and lightwave applications) is showcasing what it claims is the first integrated, single-chip transmit and receive (TX/RX) solution for short-reach 100G optical transceiver modules, active optical cables (AOCs) and on-board optical engines.
The seamless integration of four-channel transmit and receive clock data recovery (CDRs), four transimpedance amplifiers (TIAs) and four vertical-cavity surface-emitting laser (VSCEL) drivers in the new MALD-37845 will afford customers unrivaled ease of use and reduced costs, says MACOM.
Supporting a full range of data rates from 24.3Gbps to 28.1Gbps, the MALD-37845 is designed for use in CPRI, 100G Ethernet, 32G Fibre Channel and 100G EDR InfiniBand applications, and will provide a low-power, single-chip solution suitable for small-form-factor optical subassemblies. It supports interoperability with a variety of VCSEL lasers and photodetectors, and is firmware-compatible with earlier-generation MACOM solutions.
“Optical module and AOC providers are under tremendous pressure to enable their customers with 100G connectivity at volume scale,” says Marek Tlalka, senior director of marketing, High-Performance Analog. “The MALD-37845 overcomes the integration and cost challenges inherent to legacy multi-chip offerings, providing an elegant, high-performance solution for short-reach 100G applications.”
The MALD-37845 100G single-chip solutions are sampling to customers now, with production availability planned for first-half 2019.
