MACOM: PAM-4 technology chipset for single lambda 100G, 200G and 400G connectivity

MACOM Technology Solutions announced a complete PAM-4 technology chipset for 100G data rates over a single wavelength enabling single fiber and four-lane parallel fiber connectivity for 100G, 200G and 400G Ethernet applications. This chipset features a new transimpedance amplifier, transmit and receive clock and data recovery devices and linear Electro-Absorption Modulated Laser driver module.

Increased traffic within and between Cloud Data Centers is driving the need for low cost 100G, and for high-speed and low power 200G and 400G interconnects. To increase bandwidth density per port, data centers OEMs are adopting faster data rates starting in 2018. These interconnects will be supported with smaller QSFP, QSFP-DD and OSFP form factor modules, which require suppliers to deliver lower power electronic components.

MACOM’s chipset addresses these power and bandwidth density needs by supporting single wavelength interconnects with EML lasers or silicon photonics, within the power envelope requirements of these smaller form factor modules.
