D.1 Power Supplies
Power is supplied from the motherboard to which the RCM3750 is connected via header
J1.
D.1.1 RCM3750
The RCM3750 has an onboard +3.3 V linear power regulator that provides the +3.3 V
supply to operate the microprocessor-related circuitry of the RCM3750. Figure D-1 shows
the power-supply circuit.
The RCM3750 requires a regulated 4.75 V to 5.25 V DC power source. An RCM3750 with
no loading at the outputs operating at 22.1 MHz typically draws 175 mA when the Ethernet
connection is active.
