AC1040F Datasheet, PDF (17/37 Pages) List of Unclassifed Manufacturers – Ultra Low Power 10/100 Quad RMII Ethernet Transceiver

AC104QF
Ultra Low Power 10/100 Quad RMII Ethernet Transceiver
connected. Energy Detect (ED) circuit is always
turned on to monitor if there is a signal energy
present on the media. The SMI circuitry is also
powered on and ready to respond to any
management transaction. The transmit circuit
still send out link pulses with minimum power
consumption. If a valid signal is received from
the media, the device will power up and resume
normal transmit/receive operation. (Patent
Pending)
3. Reduced Transmit Drive Strength mode:
Additional power saving can be gained at the
Phy level by designing with 1.25:1 turns ration
magnetic and asserting the TP125 pin at reset.
CLOCK
The clock input must a TTL clock oscillator
measured at 50 MHz-100PPM.
