MediaTek unveils low power 800GbE PHYs for data centres, 5G infrastructure

Friday 31 July 2020 | 10:22 CET | News

MediaTek announced the commercial availability of its MT3729 product family of 800GbE (Dual 400GbE) MACsec retimer PHYs designed for the high-speed and ultra-low power data transmissions needs of data centres and 5G infrastructure applications, in addition to the stringent security requirements of these applications. 

The MT3729 family uses MediaTek’s 56G PAM4 SerDes technology available as a standalone application-specific standard part (ASSP), and will equip Tier-1 network equipment and service providers to enable secure, reliable and high-speed data transfer for modem networking infrastructure. 

The MT3729 product family is ideal for line cards or switch fabrics to build multi-terabit network servers, switches and routers with secure high-speed data links and highly accurate Class-C precision time protocol (PTP) timestamping features.

The MT3729 product family delivers four different operation modes: Retimer Mode; Forward/Reverse Gearbox Mode; MUX/DeMUX Mode, as well as MACsec Mode. 

The MT3729 product family supports up to 16 bi-directional links at 56G PAM4, up to 28G NRZ SerDes and 1G SGMII. And since 5G networks will require tighter timing synchronisation, the MT3729 family supports IEEE 1588v2 and SyncE up to Class-C for greater accuracy and more flexibility with timestamping formats. 

The MediaTek’s MT3729 product family is available now, with the first customer products already in development.
