Port 3 and Port 4 support either MII or RMII interfaces with SW3-MII/RMII and SW4-MII/RMII (see Functional Diagram) for KSZ8864CNX/RMNUB data interface. An industrial temperature-grade version of the KSZ8864CNXIA and a qualified AEC-Q100 Automotive version of the KSZ8864RMNUB are also available (see the Ordering Information section).The KSZ8864CNX/RMNUB provides multiple CPU control/data interfaces to effectively address both current and emerging fast Ethernet applications. The KSZ8864CNX/RMNUB consists of 10/100 fast Ethernet PHYs with patented and enhanced mixed-signal technology, media access control (MAC) units, a highspeed non-blocking switch fabric, a dedicated address lookup engine, and an on-chip frame buffer memory. The KSZ8864CNX/RMNUB contains four MACs and two PHYs. The two PHYs support the 10/100Base-T/TX. All registers of MACs and PHYs units can be managed by the control interface of SPI or the SMI.
