Part Number: DS92LX1622
Other Parts Discussed in Thread: DS92LX1621,

Hello to whom it may concern,

Could you please teach me about below question?

Q1; How much internal pull-down resistance value of PDB(#9 pin)?
Q2; How much internal pull-up resistance value of M/S(#8 pin)?

Best regards,

Manabu Ito

    Hi Manabu,

    Thank you for reaching out to us. If you are referring to PDB (pin#9), the device is DS92LX1621 (Serializer) on page 3 of datasheet.

    For Deserializer DS92LX1622, both PDB and M/S are active weak pull up/down pins. The internal pull up/down resistance is megaohm. The leakage current is less than 20uA. We are recommended to use external pull up/down resistors on the system board.

    Please let me know if you have additional question.

    Regards,
    Dennis
