No Preview Available ! KS8995 – 5 Port 10/100 Switch with PHY
Introduction
The KS8995 contains five 10/100 physical layer
transceivers, five MAC (Media Access Control) units
with an integrated layer 2 switch. The device runs in
two modes. The first mode is a five port integrated
switch and the second is as a five port switch with the
fifth port decoupled from the physical port. In this
mode access to the fifth MAC is provided using a
MII (Media Independent Interface).
Useful configurations include a stand alone five port
switch as well as a four port switch with a routing
element connected to the extra MII port. The
additional port is also useful for public network
interfacing.
The KS8995 is designed to reside in an unmanaged
design not requiring processor intervention. This is
achieved through I/O strapping at system reset time
On the media side, the KS8995 supports 10BaseT,
100BaseTX and 100BaseFX as specified by the IEEE
802.3 committee.
Physical signal transmission and reception are
enhanced through use of analog circuitry that makes
the design more efficient and allows for lower power
consumption and smaller chip die size.
• Unmanaged operation via strapping at system
reset time
• Hardware based 10/100, full/half, flow control
and auto negotiation
• Individual port forced modes (full duplex,
100BaseTX) when auto negotiation is disabled
• Wire speed reception and transmission
• Integrated address Look-Up Engine, supports 1K
absolute MAC addresses
• Automatic address learning, address aging and
address migration
• Broadcast storm protection
• Full duplex IEEE 802.3x flow control
• Half duplex back pressure flow control
• Comprehensive LED support
• External MAC interface (MII or SNI) for router
applications
