... Freescale Semiconductor, Inc. Power Supply Filtering The MPC961C is a mixed analog/digital product and as such it exhibits some sensitivities that would not necessarily be seen on a fully digital product. Analog circuitry is naturally susceptible to random noise, especially if this noise is seen on the power supply pins. The MPC961C provides separate power supplies for the output buffers ( and the phase– ...

The voltage wave launched down the two lines will equal ( +Zo 3.0 ( 25) = 3.0 (25 / 57) = 1.31V At the load end the voltage will double, due to the near unity reflection coefficient, to 2.62V. It will then increment towards the quiescent 3.0V in steps separated by one round trip delay (in this case 4 ...
