7.2.11
Power Reduced Mode
The Signal detect circuit is always turned on to monitor
whether there is any signal on the media. In case of cable
disconnection,, DM9161 will automatically turn off the power
and enter the Power Reduced mode, regardless of its
operation mode being N-way auto-negotiation or forced
mode. While in the Power Reduced mode, the transmit
circuit will continue sending out fast link pules with minimum
power consumption. If a valid signal is detected from the
media, which might be N-way fast link pules, 10Base-T
normal link pules, or 100Base-TX MLT3 signals, the device
wakes up and resumes normal operation mode.
Automatic reduced power down mode can be disabled by
writing Zero to Reg.16.4.
7.2.12 Power Down Mode
Power Down mode is entered by setting Reg.0.11 to ONE or
pulling PWRDWN pin high, which disables all transmit and
receive functions, and MII interface functions except the
MDC/MDIO management interface.
7.2.13 Reduced Transmit Power Mode
Additional transmit power reduction can be gained by
designing with 1.25:1 turns ration magnetic on its TX side
and using a 8.5K
Ω
resistor on BGRES and BGRESG pins,
and the TX+/TX- pulled high resistors being changed from
50
Ω
to 78
Ω
. This configuration could reduce about 20% of
transmit power.
