1. The MPC905 can drive 50

W transmission lines on the incident edge. Each output drives one 50W parallel terminated transmission line to

VTT = VCC/2. Alternately, the device drives up to two 50W series terminated transmission lines per output.

2. XTAL_IN input will sink up to 10mA when driven to 5.5V. There are no reliability concerns associated with the condition. Note that the Enable1

input must be a logic HIGH. Do not take the Enable1 input to a logic LOW with >VCC volts on the XTAL_IN input.
