SEMICONDUCTOR TECHNICAL DATA  
The MPC9993 is a PLL clock driver designed specifically for redundant  
clock tree designs. The device receives two differential LVPECL clock  
signals from which it generates 5 new differential LVPECL clock outputs.  
Two of the output pairs regenerate the input signals frequency and phase  
while the other three pairs generate 2x, phase aligned clock outputs.

Functional Description  
The MPC9993 Intelligent Dynamic Clock Switch (IDCS) circuit continuously monitors both input CLK signals. Upon detection  
of a failure (CLK stuck HIGH or LOW for at least 1 period), the INP_BAD for that CLK will be latched (H). If that CLK is the primary  
clock, the IDCS will switch to the good secondary clock and phase/frequency alignment will occur with minimal output phase  
disturbance. The typical phase bump caused by a failed clock is eliminated. (See Application Information section).
