Speaking of MediaTek, many people must have thought of its mobile phone chips for the first time, but like any tech giant, MediaTek’s business is much more. Recently, MediaTek released the 800GbE (dual-port 400GbE) MACsec retimer PHY transceiver “MT3729” series, aimed at data centers and 5G infrastructure, to meet their high-speed, ultra-low-power data transfer, and stringent security requirements.
The MediaTek MT3729 series is based on its 56G PAM4 SerDes technology to help tier-one network equipment and service providers enable secure, reliable and high-speed data transmission for network infrastructure.
The MT3729 series supports up to 16 56G PAM4 bidirectional links, up to 28G NRZ SerDes, 1G SGMII, and IEEE 1588v2 and high-precision Class-C SyncE to meet the stringent timing requirements of 5G infrastructure.
The MT3729 series has four different modes of operation:
– Retimer mode.
Built-in signal enhancement technology extends SerDes connection distance and transmission to end devices for more accurate timestamps.
– Forward/Reverse Transmission (Gearbox) mode.
Supports bitrate conversion between 56G and 28G links, enabling next-generation switches to seamlessly connect to existing infrastructure.
– MUX/DeMUX mode.
Non-disruptive MUX and broadcast exchange to meet network backup requirements.
– MACsec mode.
Supports IEEE 802.1AE MACsec for secure communication from 1GbE to 400GbE per port via AES-128, AES-256 encryption.
The MT3729 series is ideal for line card or switch structures to build very large bandwidth, ultra-high-rate network servers, switches, and routers with secure high-speed data links and high-precision Class-C PTP timestamps.
MediaTek said the MT3729 series is now on the market and the first customer products are already under development.
