UPD60620AGK-GAK-M1-AX

The extended dual-channel 10/100 Ethernet PHYs uPD60620 is fully integrated Physical layer devices to connect to standard IEEE802.3 Ethernet networks. Today’s industrial networking standards often implement daisy-chain or ring structures, in which a dual-channel PHY configuration makes a perfect fit.These devices specifically focus on low latency and low jitter to support today’s industrial Ethernet standards. In addition, the uPD60621A features hardware support for IEEE1588 V2. Renesas Electronics’ specific enhanced diagnosis features allow permanent cable quality monitoring for easy maintenance in factory automation applications.The PHY can connect to unshielded twisted-pair (UTP) cable via external magnetic or to optical fiber via fiber PMD modules. It interfaces to an Ethernet MAC layer through the IEEE 802.3 Standard Media Independent Interface (MII) or reduced MII (RMII) interface.The uPD60621A also includes support for PTP according to IEEE1588 Version 1 and 2. To support this, an 80-bit clock is included in the PHY. Timestamps with a resolution of as low as 1ns can be taken from received and transmitted frames and events on external pins. The device also supports one-step and two-step timestamp insertion and supports transparent mode.
