TIME SYNC
TIME SYNC
Time Sync is an independent clock data transfer system that was developed
to eliminate recovery jitter. Time Sync couples the high speed master clock
output from the transport directly to the processor. This means there is one
system master clock for the transport and processor. The use of the Time Sync
system requires that a KRELL processor be equipped with a Time Sync input.
It also requires that the Time Sync output of the KPS-20t be connected to the
Time Sync input of the processor using an ST fiber optic cable.
With Time Sync operating, the processor does not use a recovered clock
generated by its decoder. Instead, the transport’s clock feeds the input of the
DACs. This process climates 100% of the jitter corruption inherent in all clock
recovery type systems. The ST interface was chosen for its high data rate and
its immunity to radiated R.F. and 60 cycle noise corruption.
Refer to the KRELL D/A Processor’s Owner’s Reference for Time Sync operating
instructions.
