DP83640
Precision PHYTER - IEEE® 1588 Precision Time Protocol
Transceiver
1.0 General Description
The DP83640 Precision PHYTER® device delivers the high-
est level of precision clock synchronization for real time in-
dustrial connectivity based on the IEEE 1588 standard. The
DP83640 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 clock generation
— Synchronized event triggering and time stamping through
GPIO
DP83640 offers innovative diagnostic features unique to Na-
tional Semiconductor, 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.
