2-Port Ethernet Switch with Non-PCI Interface and
10B-FL / 100B-SX / 100B-FX Support
Description
The KSZ8862-16MQL (or -32MQL) is the industry’s first
fully managed 2-port switch with a non-PCI CPU interface.
It is similar to the KSZ8842-16MQL (or –32MQL) family,
however port-1 supports fiber mode, while port-2 supports
10B-T / 100B-TX. It is based on a proven, 4th generation,
integrated Layer 2 switch that is compliant to the IEEE
802.3u standard.
The KS8862-16MQL (or –32MQL) contains two 10/100
transceivers with patented mixed-signal low-power
technology, two media access control (MAC) units and a
direct memory access (DMA) channel, a high-speed nonblocking
switch fabric, a dedicated 1K entry forwarding
table, and an on-chip frame buffer memory. In fiber mode,
the port-1 PHY can be configured to 100BASE-FX,
100BASE-SX, or 10BASE-FL fiber. Port-2 supports
10BASE-T and 100BASE-TX, which therefore makes the
devices ideal for use in managed Media Converter
applications. An LED driver and post amplifier are also
included on-chip for 10Base-FL applications, thus making
for a very cost effective solution.
The KS8862-16MQL (or –32MQL) offers an extensive
feature set that includes tag/port-based VLAN, QoS priority
management, MAC filtering, MIB counters, and CPU
control/data interfaces to effectively address both current
and emerging Fast Ethernet applications.
