Ethernet Product Highlight — Low Power, Small Package
The KSZ8895MQ/RQ/FMQ is a highly-integrated Layer 2 managed five-port
switch with optimized design and plentiful features. It is designed for cost-
sensitive 10/100Mbps five-port switch systems with lowest power consump-
tion, on-chip termination and internal core power controller. These features
will save more system cost. It supports high-performance memory bandwidth,
shared memory based switch fabric with 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, four queues QoS prioritization, management interfaces and MIB
counters. KSZ8895 family provides multiple CPU data interfaces to effec-
tively address both current and emerging fast Ethernet applications when
port 5 is configured to apart MAC5 with SW5 and PHY5 with P5-MII/RMII
interfaces.
The configurations provided by the KSZ8895 family enables the flexibility
to meet different requirements:
KSZ8895MQ: Five 10/100Base-T/TX transceivers, one SW5-MII and one
P5-MII interface.
KSZ8895RQ: Five 10/100Base-T/TX transceivers, one SW5-RMII and one
P5-RMII interface.
KSZ8895FMQ: Three 10/100Base-T/TX transceiver on Ports 1, 2, 5 and
two 100Base-FX transceivers on Ports 3, 4, one SW5-MII and one P5-MII
interface.

The KSZ8051/8031/8021 family of ultra low-power, small package single-
port 10/100 Physical Layer Transceivers. The ICs provide the MII or RMII
interface to transmit and receive data over standard CAT-5 unshielded
twisted pair (UTP) cable or fiber. The solution is based on Micrel's enhanced
mixed-signal design which enables power consumption to be reduced by
half compared to the prior generation. The devices feature high integration
(on-chip termination and integrated regulator), reduced system cost and
simplified system design. The ICs also feature higher performance and an
extended feature set all in very compact package options.
Energy efficiency and compliance to important green standards such as
ENERGY STAR are becoming paramount in the digital home making Micrel's
new devices a key enabler for the pervasive adoption of IP connectivity in
devices such as Digital TVs, Set-Top-Boxes and media players. The low
emissions and Micrel's signature high reliability and quality also make these
devices suitable for connectivity applications in the fast growing industrial
automation and automotive markets.
Full compliance to the IEEE 802.3/802.3u standard ensures that the devices
will work seamlessly with other standards compliant, already deployed
devices. The ultra low power design satisfies the green requirement in
today's consumer, industrial and automotive Ethernet applications. On-chip
termination not only eliminates components, simplifies PCB design and
reduces system BOM, but also improves overall signal integrity and EMI
emissions. The single external power supply (3.3V), with integrated regulator,
enables core operation at 1.2V with IO at 1.8V/2.5V/3.3V. The KSZ8051MLL/
FLL comes in a 48-pin LQFP package and provides a MII MAC interface
with the option to interface to copper or fiber media. The KSZ8051MNL/
RNL is a copper transceiver housed in a 32-pin QFN with the option for
a MII or RMII MAC interface. The KSZ8031RNL and KSZ8021RNL offer
the smallest package, 24-pin QFN, with an RMII MAC interface. Auto MDI/
MDIX crossover support eliminates the need for a cross-over cable, thus
reducing installation costs. Easy to use, the LinkMD
diagnostics allow for identification of common cabling problems, including
those not addressed by IEEE standards. This simplifies network deployment
and reduces network downtime.
