DP83848 Series Current driver class A or B?

Hi Jim,

You will see in the datasheets that the Manchester data is pre-emphasized. We do not disclose the type of drivers we use internally. What is the purpose for this inquiry?

Kind regards,
Ross

Thank you for the answer on pre-emphasis.

We potentially plan to use this transceiver to drive a low cost industrial plastic optical fiber link at 10Mbps, rather than to drive copper. Knowledge of the class of Tx driver, A or B, will enable us to decide what interface we require to drive the photonics. Class B drivers might prove usable directly from the Tx- pin, rather than using an otherwise unnecessary Ethernet transformer in-between. Without the datasheet (or tech support) stating this mundane information directly, we would need to scope out the MDI to empirically determine what the IC design implemented.

For example, Marvell states driver class information in their confidential app notes. I maintain some hope that TI could provide this information for their own PHYs as well.
