RBIAS

RBIAS requires external resistor connection to bias the internal analog section of the
device. The input is sensitive to the resistor value. Resistors of 1% tolerance must be
used. Connect RBIAS through a 4.87 k 1% pull-down resistor to ground and then
place itno more than one half inch (0.5") away from the PHY.
