Micrel (San Jose, CA) has launched the KSZ8895/8875/8864 series of low-
power, highly integrated, 4/5-port Layer-2 switch-on-a-chip
ICs. Leveraging Micrel’s latest green physical transceiver and switch
technology, the product family achieves a 50 percent reduction in power
consumption compared to the previous generation and features advanced
power management and sophisticated Quality of Service (QoS)
capabilities. The devices support a single 3.3V power supply with an
internal 1.2V LDO, with options for 3.3V, 2.5V or 1.8V IO
voltages. Further power savings are supported by advanced power
management, including the device’s “Energy Detect Power Down”
mode. This mode is activated when the cable is unplugged, and the
“slow oscillator” mode is activated when the device is not in use.
