KSZ8893FQL

KSZ8893FQL Single-Chip 3-Port Switch with Fiber Support Rev. 1.3 General Description The KSZ8893FQL, a highly integrated single-chip 3 port Fast Ethernet switch is designed for applications with fiber support such as media converter. It provides two 10/100 transceivers with patented mixed-signal lowpower technology, three media access control (MAC) units, a high-speed non-blocking switch fabric, a Layer-2 managed switch and TS-1000 OAM (Operations, Administration and Management) V2 in a compact solution. Backwards compatible to the TS-1000 (2002) specification, TS-1000 V2 is an OAM sub-layer that provides communication between CO (central office) and CPE (customer premises equipment). In fiber mode, one PHY unit can be configurable to 100Base-FX, 100Base-SX, or 10Base-FL fiber for conversion to 10Base-T and 100Base-TX copper. A fiber LED driver and post amplifier are also included for 10Base-FL and 100Base-SX applications. LinkMD® In copper mode, both PHY units support 10Base-T and 100Base-TX with HP Auto MDI/MDI-X for reliable detection of and correction for straight-through and crossover cables, and LinkMD® TDR-based cable diagnostics for identification of faulty cabling. The high performance switching engine features an extensive feature set that includes programmable rate limiting, tag/port-based VLAN, 4 priority class, RMII/MII/SNI and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications.
