... In the x1 and x1.5 modes the QFB output will produce 50% duty cycle signals. The MPC932 provides two pins for use in system test and debug operations. The MR/OE input will force all of the outputs into a high impedance state to allow for back driving the outputs during system test. In addition the PLL_EN pin allows the user to bypass the PLL and drive the outputs directly through the Ref_CLK input ...

... V CC /2. This technique draws a fairly high level of DC current and thus only a single terminated line can be driven by each output of the MPC932 clock driver. For the series terminated case however there current draw, thus the outputs can drive multiple series terminated lines. ...
