Part Number: LMK04828

Hello Team,

May I know the minimum LOS detection frequency of CLKin0? 

Customer want to detect LOS of CLKin0 port under this condition. 

CLKin0 : 80kHz, MOS

CLKin_SEL0 : Oputput(push-pull), CLKin0 LOS

Even though customer check that CLKin0 is good and LD1, LD2 are lock, LOS reported as high. It seems like CLKin0 frequency is too low to detect proper LOS detect. 

Best regards,
