Interfacing the MC68EN360 to an Ethernet SIA Applications Information

PublishTime：2021-11-24

●This document describes the interface between the MC68EN360 and Ethernet. Any of the SCCs on the MC68EN360 can be confiqured in Ethernet mode. For performance reasons, however, not all SCCs on the MC68EN360 can be confiqured into Ethernet mode at the same time. If an MC68EN360 is operating at 25MHz.up to two SCCs can be confiqured for Ethernet simultaneously. With this confiquration there will be at least 1 Mbps full duplex HDLC bandwidth left for an additional SCC. If an MC68EN360 is operating at 33MHz up to three SCCs can be contigured for Ethernet simultaneously.
●For this application note, the AM7992B is used as the serial interface adapter (SIA). (The MC68360 user's manual shows the connection to the MC68160 EEST from Motorola) The interface between the MC68EN360 and the SIA does not require any glue logic, as shown on Figure 1. For simplicity in the diagram the actual pin names on the MC68EN360 have been omitted for a specitic SCC.
