be latched (H).
If that CLK is the primary clock, the device 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.
FEATURES
GENERAL DESCRIPTION
The XRK7955 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 thre...
