Intelligent Dynamic Clock
Switch (IDCS) PLL Clock
Driver
The MPC99J93 is a PLL clock driver designed specifically for redun-
dant 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.
Features:
Fully Integrated PLL
Intelligent Dynamic Clock Switch
LVPECL Clock Outputs
LVCMOS Control I/O
3.3V Operation
32--Lead LQFP Packaging
Functional Description
The MPC99J93 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).
