CommProcessor. The 380C26 is compatible with Mode 4 (MD0 and MD1 both high).
When you use the LXT905 Transceiver with the 380C26, you can tie both the LXT905
Transceiver and a TMS38054* Token Ring transceiver to a single RJ-45, allowing dual
network support from a single connector.
Optional: Center tap capacitor may improve EMC depending on board layout and system design.
