Memory system OFF

(MSON=L)

Note. When the memory system is OFF (through mode), the input data rate is synchronized to the system clock input (384fs), so input

data needs to be at 1/384 of this frequency. But, this IC can tolerate a certain amount of jitter. For details, refer to Through-mode

operation.
