Product description
The AX88873 10/100Mbps Dual Speed repeater Controller is a counterpart of AX88872 without built in 4-ports switch. It is design for low cost dual speed dumb HUB application. The AX88873 directly supports up-to eight 10/100Mbps automatic links RMII interfaces. Maximum up-to 96 repeater ports can be constructed by stacking 1 AX88872 and 2 AX88873 chips horizontally and then cascading 4 horizontal boards vertically. With using 128-pin low cost package, accompany with AX88872 to build up low cost dual speed repeater application. Not only perform the repeater function but gain additional 2 switch ports. The 2 dual speed switch ports are connected to exte……
