DS90UB954-Q1: wait time after pdb release

Ryan Wang

Part Number: DS90UB954-Q1

Dear expert,

How long should I wait between PDB rise to high to UB954 register programing?

How long it takes for UB954 and UB953 to LOCK?

Thanks

Hi Ryan,

The wait time after PDB release before programming UB954 registers is >2ms.

The UB954 forward channel lock time is below:

The UB953 back channel lock time is typically about 60 ms.

Best regards,

Anthony
