MACOM expands 5G optical connectivity portfolio with 28Gbps TIAs

MACOM announced the sampling and pre-production of the new 28Gbps transimpedance amplifiers (TIA), including the MATA-03003 and MATA-03006 devices. This high-performance TIA solution supports data rates from 8.5 Gbps to 28 Gbps for 25G CPRI, 25G Ethernet and 32G Fibre Channel applications while featuring low power, high sensitivity/overload, reduced die size and flexibility in optical sub-assembly (OSA) for SFP28 optical modules.

Driven by 5G connectivity, data traffic demand is growing rapidly in wireless, enterprise and Cloud Data Center applications. Optical module customers are continually looking for ways to deliver lower power, smaller size and lower cost solutions. MACOM’s new TIA devices offer a 20% power reduction, while providing improved sensitivity and extended overload performance, enabling the TIAs to be cost effective and ideal in high density optical connectivity solutions. MACOM’s new TIA solution reduces the need for external components, streamlining hermetic To-header or chip-on-board assembly.

MACOM’s MATA-03003 family of devices offer die pinout flexibility in optical sub-assembly, allowing them to be assembled in various To-headers with PIN detectors for short reach (SR) and long reach (LR) applications, while the MATA-03006 can be assembled with high performance APDs for extended reach (ER) applications. The new TIA devices feature a selectable low rate mode operation via RSSI control pin from 28G VCSEL and DML laser driver with integrated CDR (MASC-37028/MALD-37030), providing an improved receiver sensitivity in low data rates and backward compatibility with legacy 10G optical modules.

The MATA-03003/3006 are available in die form only. Pre-production samples are available today with expected production release in the first half of 2018.
