1. When using External Source for reference, requirement to meet PCI clock duty cycle requirement on the output.
1. The MPC905 can drive 50Ω transmission lines on the incident edge. Each output drives one 50Ω parallel terminated transmission line to
2. XTAL_IN input will sink up to 10mA when driven to 5.5 V. There are no reliability concerns associated with the condition. Note that the
1. Assuming input duty cycle specs from Recommended Operating Conditions table are met.
2. Assuming external crystal or 50% duty cycle external reference is used.
