Description
The KSZ8842-PMQL is the industry’s first 2-port switch
with a PCI CPU interface. An Industrial Temperature
grade part, the KSZ8842-PMQLI will also available from
Q1, 2006. The KSZ8842P is a proven, 4th generation,
integrated, fully managed Layer 2 switch that is entirely
compliant to IEEE802.3u standards.
The KSZ8842P can be configured as a low-latency repeater
to allow for ‘cut thru’ in latency critical Embedded or
Industrial Ethernet applications. For industrial automation
applications, it runs in half-duplex mode.
The KSZ8842P offers an extensive feature set that includes
tag/port-based VLAN, QoS priority management, MAC
filtering function, MIB counters, and CPU control/data
interfaces to effectively address both current and emerging
Fast Ethernet applications.
The KSZ8842P contains two 10/100 transceivers with
patented mixed-signal low-power technology, two 1K
entry media access control (MAC) units, a separate
DMA channel, a high-speed non-blocking switch fabric,
a dedicated 1K entry forwarding table, and an on-chip
frame buffer memory.
