About input and output duty cycle of CDCM6208

CDCM6208 datasheet written about input/output duty cycle below.

・Page 9  ：IDC (Deference Input Duty Cycle) ⇒ 40%～60% 

・Page 12：ODC (Output Duty Cycle)              ⇒ 45%～55%

If custoer's input duty cycle is narrow range (48%～52%), will output duty cycle be narrow range, too?

If correct, is output duty cycle less than 48%～52% or more narrow?

Best regards,
