ONET8501PB: Default status of Outputs and default output Amplitude

Expert 8760 points
Part Number: ONET8501PB

Hi team,

My customer wants to know ONET8501PB default status of outputs and default output amplitude.

ONET8501PB has Dis pin and DIS register bit.

I have following 3 questions.

(1) Which one is given priority? Is it pin or register bit?

(2) Which one is default register bit status? Is it 0 or 1?

(3) How much is the default output amplitude?

Please let me know.

Best regards,
Fumio Nakano

  • Hi Fumio-san,

    Here are my response to the customer's questions:

    (1) Which one is given priority? Is it pin or register bit?

    Sri: For the device output to be enabled for ONET8501PB, both DIS pin and the DIS register bit must be set to "enable" configuration. That is, DIS pin should be low and DIS register bit must be set to "0". 

    (2) Which one is default register bit status? Is it 0 or 1?

    Sri: The default register bit status is "0", i.e., it is in enabled state.

    (3) How much is the default output amplitude?

    Sri: I believe the default amplitude-select bits, AMP1 and AMP0 are 0 and 1. For ONET8501PB, this corresponds to an output amplitude of VOD = 650mVpp;

    Hope this helps, please let me know for further clarifications.

    Thanks,

    Sri
