DP83910A CMOS SNI  
Serial Network Interface  
General Description  
The DP83910A CMOS Serial Network Interface (SNI) is a  
direct-pin equivalent of the bipolar DP8391 SNI and pro-  
vides the Manchester data encoding and decoding func-  
tions for IEEE 802.3 Ethernet/Thin-Ethernet type local area  
networks. The SNI interfaces the DP8390 Network Interface  
Controller (NIC) to the DP8392 CTI or an Ethernet transceiv-  
er cable. When transmitting, the SNI converts non-return-to-  
zero (NRZ) data from the controller into Manchester data  
and sends the converted data differentially to the transceiv-  
er. Conversely, when receiving, a Phase Lock Loop de-  
codes the 10 Mbit/s data from the transceiver into NRZ  
data for the controller.  
DP83910A, fabricated CMOS, typically consumes less than  
70 mA of current. However, as a result of being CMOS, the  
DP83910A’s differential signals must be isolated in both  
Ethernet and thin wire Ethernet.  
Features  
Y
Compatible with Ethernet I, IEEE 802.3; 10BASE5,  
10BASE2, and 10BASE-T  
Y
Designed to interface with 10BASE-T transceivers  
Y
Functional and pin-out duplicate of the DP8391  
Y
10 Mbits/s Manchester encoding/decoding with receive  
clock recovery  
The DP83910A operates in conjunction with the DP8392  
Coaxial Transceiver Interface (CTI) and the DP8390 Net-  
work Interface Controller (NIC) to form a three-chip set that  
implements a complete IEEE 802.3 compatible network as  
shown below. The DP83910A is a functionally complete  
Manchester encoder/decoder including a balanced driver  
and receiver, on-board crystal oscillator, collision signal
