ANALOG 5V SUPPLY PIN This pin supplies 5V to the DP83907’s analog circuitry To
maximize data recovery it is recommended that analog layout and decoupling rules be
applied between this pin and AGND
ANALOG NEGATIVE (GROUND) SUPPLY PIN
PHYSICAL MEDIA 5V SUPPLY PINS This pin supplies 5V to the DP83907’s analog
physical media interface circuitry
PHYSICAL MEDIA NEGATIVE (GROUND) SUPPLY PINS This pin is the ground to the
DP83907’s analog physical media interface circuitry
POSITIVE 5V SUPPLY PINS These pins suppy power to the DP83907
NEGATIVE (GROUND) SUPPLY PINS These are the supply pins for the DP83907 It is
suggested that decoupling capacitors be connected between the V
is essential to provide a path to ground for the GND pins with the lowest possible
impedance
