1.3 Description

The DP83630 Precision PHYTER™ device delivers the highest level of precision clock synchronization for

real time industrial connectivity based on the IEEE 1588 standard. The DP83630 has deterministic, low

latency and allows choice of microcontroller with no hardware customization required. The integrated 1588

functionality allows system designers the flexibility and precision of a close to the wire timestamp. The

three key 1588 features supported by the device are:

— Packet time stamps for clock synchronization

— Integrated IEEE 1588 synchronized low jitter clock generation

— Synchronized event triggering and time stamping through GPIO

DP83630 offers innovative diagnostic features unique to Texas Instruments, including dynamic monitoring

of link quality during standard operation for fault prediction. These advanced features allow the system

designer to implement a fault prediction mechanism to detect and warn of deteriorating and changing link

conditions. This single port fast Ethernet transceiver can support both copper and fiber media.
