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-to-zero (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.
The DP83910A operates in conjunction with the DP8392 Coaxial Transceiver Interface (CTI) and the DP8390 Network 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 translator, and a diagnostic loopback feature. The 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.
