Intelligent Dynamic Clock Switch
(IDCS) PLL Clock Driver
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).
