An integrated, single-chip transmit and receive solution for short reach 100G optical transceivers, active optical cables (AOCs) and onboard optical engines has been announced by MACOM. 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 within the new MALD-37845 will afford customers unrivaled ease of use and reduced costs.

Supporting a full range of data rates from 24.3-28.1Gbps, the new MALD-37845 is designed for use in CPRI, 100G Ethernet, 32G Fibre Channel and 100G EDR InfiniBand applications, and will provide customers with a low power, single-chip solution well suited for small form-factor optical subassemblies.

The MALD-37845 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,” said Marek Tlalka, Senior Director of Marketing, High Performance Analog, MACOM. “We believe that 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.”

MACOM’s MALD-37845 100G single-chip solutions are sampling to customers today, with production availability planned for the first half of 2019.

MACOM will be showcasing the new MALD-37845 at the European Conference on Optical Communication (ECOC), Booth #579, in Rome, Italy, 24th-26th September.
