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:  
3.0 Features  
IEEE 1588 V1 and V2 supported  
UDP/IPv4, UDP/IPv6, and Layer2 Ethernet packets  
supported  
IEEE 1588 clock synchronization  
Timestamp resolution of 8 ns  
Allows sub 100 ns synchronization to master reference  
12 IEEE 1588 GPIOs for trigger or capture  
— Packet time stamps for clock synchronization  
Deterministic, low transmit and receive latency  
— Integrated IEEE 1588 synchronized clock generation  
Selectable frequency synchronized clock output  
— Synchronized event triggering and time stamping through  
GPIO  
Dynamic Link Quality monitoring  
TDR based Cable Diagnostic and Cable Length Detection  
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.  
10/100 Mb/s packet BIST (Built in Self Test)  
Error-free Operation up to 150 meters CAT5 cable  
ESD protection - 8 kV human body model  
3.3 V I/Os and MAC interface  
Auto-MDIX for 10/100 Mbps  
RMII Rev. 1.2 and MII MAC interface  
25 MHz MDC and MDIO Serial Management Interface  
2.0 Applications  
IEEE 802.3u 100BASE-FX Fiber Interface  
Factory Automation  
IEEE 1149.1 JTAG  
Ethernet/IP  
CIP Sync  
Programmable LED support for Link, 10 /100 Mb/s Mode,  
Duplex, Activity, and Collision Detect  
Test and Measurement  
Optional 100BASE-TX fast link-loss detection  
LXI Standard  
48 pin LQFP package (7mm) x (7mm)  
Telecom  
Basestation  
Real Time Networking
