DS36954: Channel to channel skew for quadrature signalling.

Mark Hosey
Prodigy 10 points
Part Number: DS36954

I'm involved in a project involving quadrature signalling using two RS485 channels. For that reason I need a figure for channel to channel skew.

Such a figure does appear on some of TI's 4 channel RS485 receivers but not always and I cannot find such a figure quoted on the DS36954 data sheet for its line receivers.

Apart for this omission the part looks ideal for my application. Though without such a figure I will be forced to look at solutions with separate quad receivers and quad transmitters.

Does such a figure exist for the DS36954?

    Mark,

    To be honest, this is an older device that TI inherited, so finding information from it's development or initial testing can be tough, but we can reach out to some teams to see if the information is available.

    We will get back to you with a response by tomorrow, thanks for your patience.

    Regards,

    Mark,

    I wasn't able to find any figures on channel to channel skew in our database for this part. As you probably read from the datasheet, we only have input to output skew listed as a parameter. Is this what you wanted, or more Channel 1 to Channel 2 skew, for example.

    Regards,
