3V 10/100BASE-TX/FX Physical Layer Transceiver Description The KS8721BL/SL is a 10BASE-T, 100BASE-TX, and 100BASE-FX physical layer transceiver providing MII/ RMII interfaces to MACs and switches.
Using a unique mixed-signal design that extends signaling distance while reducing power consumption, the KS8721BL/SL represents Micrel’s fourth generation single-port Fast Ethernet PHY.
Micrel’s architecture dissipates an ultra-low 275mW in power, including transmit output drivers.
This translates to increased reliability while enabling deployment in today’s power-sensitive applications.
Multiple power-down modes, accessed via config...
