Single chip is first 100G bi-directional optical connectivity module, says Macom

Integrating clock data recovery, transimpedance amplifier and vertical cavity surface emitting laser (VSCEL) drivers, the MALD-37845 is claimed to be the industry’s first integrated, single-chip transmit and receive solution for short reach 100G optical transceivers, active optical cables and on-board optical engines.

The seamless integration of four-channel transmit and receive clock data recovery, four transimpedance amplifiers and four VSCEL drivers offers ease of use and reduced costs, says Macom.

The module supports a range of data rates from 24.3 to 28.1Gbits per second, and is designed for use in CPRI, 100G Ethernet, 32G Fibre Channel and 100G EDR InfiniBand applications. The low power, single chip is suitable for small form factor optical subassemblies, says Macom. The MALD-37845 supports interoperability with a variety of VCSEL lasers and photodetectors, and is firmware-compatible with earlier-generation Macom devices.

Marek Tlalka, senior director of marketing, high-performance analog at Macom, said: “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.”

The MALD-37845 will be showcased at ECOC this month and is sampling to customers now. Production availability is planned for the first half of 2019.
