KSZ8895MLUB
Integrated 5-Port 10/100 Managed Switch
Revision 2.1 General Description
The KSZ8895MLUB is a highly-integrated Layer 2managed 5-port switch with an optimized design and
plentiful features, qualified to meet AEC-Q100 standard
for automotive applications. It is designed for costsensitive 10/100Mbps 5-port switch systems with on-chip
termination, lowest power consumption and internal core
power controller. These features will save more system
cost. It has 1.4Gbps high-performance memory
bandwidth, shared memory based switch fabric with full
non-blocking configuration. It also provides an extensive
feature set such as power management, programmable
rate limit and priority ratio, tag/port-based VLAN, packets
filtering,
quality-of-service
(QoS)
four-queue
prioritization, management interface, and MIB counters.
Port 5 is a MAC 5 MII interface with PHY mode as
default at switch side. The SW5-MII interface can be
connected to a processor with a MAC MII interface. The KSZ8895MLUB consists of 10/100 PHYs with
patented and enhanced mixed-signal technology, media
access control (MAC) units, a high-speed non-blocking …
