Other Parts Discussed in Thread: DP83822EVM
Posting on behalf of my customer.
"The optical fiber interface that we are using is not a standard LED driver/detector type, but has LVDS interfaces. We have had problems interfacing the LVDS fiber transceiver to a 10/100 PHY from Broadcom in the past as it had PECL interfaces causing a signal level mismatch. What type of interface is used on the DP83822IF for the TD/RD pins so that I can make sure we are successful interfacing the PHY to the LVDS signals? Based on our experience, we do not believe that connecting the transceiver as per the TI datasheet recommendations will give us proper operation."
