The DP83910A CMOS Serial Network Interface (SNI) is a direct-pin equivalent of the bipolar DP8391 SNI and provides the Manchester data encoding and decoding functions 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 transceiver cable When transmitting the SNI converts non-return-tozero (NRZ) data from the controller into Manchester data and sends the converted data differentially to the transceiver Conversely when receiving a Phase Lock Loop decodes the 10 Mbit s data from the transceiver into NRZ data for the controller
