AC characteristics  
Standard voltage: VDD1 = VDD2 = 4.5 to 5.5 V, VSS = 0 V, Ta = -40 to 85 ˚C  
Low-voltage: VDD1 = VDD2 = 2.4 to 4.5 V, VSS = 0 V, Ta = -20 to 70 ˚C  
(*) Typical values are for fs = 44.1 kHz

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.
