Question about Broadcast command of LTC6811-2 (with addressable interface)

Category: Datasheet/Specs
Product Number: LTC6811-2

Hello,

My customer is reviewing the  LTC6811-2 and they have a question about the format of Broadcast write command.

At the format in LTC6811-2 Datasheet   is like below.

And the format in LTC6804-2 Datasheet is like below.

Should they add Shift byte 1 ...Shift byte N bytes for using Broadcast Write command in LTC6811-2?

If they should add these bytes, would you let me know why these bytes are added eventhough they use a addressable interface?

Please let me know.

Regards,

Se-woong

  • These are not needed when using the LTC68xx-2 parts.  Broadcast commands will write the same data or perform the same action on all attached LTC68xx-2 devices.  If different data is needed on an individual monitor, the address commands should be used instead rather than shifting in different data to each device in a daisy-chain as is the case in LTC68xx-1.
