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.
