Power Management
The KSZ8041NL/RNL offers the following power management modes:
Power Saving Mode
This mode is used to reduce power consumption when the cable is unplugged. It is in effect when auto-negotiation mode
is enabled, cable is disconnected, and register 1F bit 10 is set to 1. Under power saving mode, the KSZ8041NL/RNL
shuts down all transceiver blocks, except for transmitter, energy detect and PLL circuits. Additionally, for the KSZ8041NL
in MII mode, the RXC clock output is disabled. RXC clock is enabled after the cable is connected and link is established.
Power saving mode is disabled by writing a zero to register 1F bit 10.
Power Down Mode
This mode is used to power down the entire KSZ8041NL/RNL device when it is not in use. Power down mode is enabled
by writing a one to register 0 bit 11. In the power down state, the KSZ8041NL/RNL disables all internal functions, except
for the MII management interface.
Reference Clock Connection Options
A crystal or clock source, such as an oscillator, is used to provide the reference clock for the KSZ8041NL/RNL.
The Figure 6 illustrates how to connect the 25MHz crystal and oscillator reference clock.

For the KSZ8041NL, Figure 7 illustrates how to connect the 50MHz oscillator reference clock for RMII mode.
