... VCO frequency range. With available output dividers of divide-by-1, divide-by-2 and divide-by-4 the internal VCO of the MPC9315 is running at either 1x the reference clock frequency. The frequency of the QA, QB, QC output groups is either the equal, one half or one fourth of the selected VCO frequency and can be configured for each output bank using the FSELA, FSELB and FSELC pins, respectively ...

... I CCQ Maximum Quiescent Supply Current a. The MPC9315 is capable of driving 50 transmission lines on the incident edge. Each output drives one 50 parallel terminated transmission line to a termination voltage Alternatively, the device drives up to two 50 series terminated transmission lines. b. Inputs have pull–up or pull–down resistors affecting the input current. ...

... AC characteristics apply for parallel output termination I/O jitter depends on VCO frequency. Please see application section for I/O jitter versus VCO frequency characteristics feedback is not available for 2.5V operation. Please see next revision of the MPC9315 for the 1 feedback option at 2.5V supply. TIMING SOLUTIONS 5 – ...

... Above equation uses the maximum I/O jitter number shown in the AC characteristic table for V CC =3.3V (10 ps RMS). I/O jitter is frequency dependant with a maximum at the lowest VCO frequency (160 MHz for the MPC9315). Applications using a higher VCO frequency exhibit less I/O jitter than the AC characteristic limit. The I/O jitter characteristics in Figure 8 ...

... Line Termination Waveforms” show the simulation results of an output driving a single line versus two lines. In both cases the drive capability of the MPC9315 output buffer is more than sufficient to drive 50 transmission lines on the incident edge. Note from the delay measurements in the simulations a delta of only 43ps exists between the two differently loaded outputs ...
