Hi,
I want to use a SN65LV124 deserializer to recover a pulse train sync signal that was serialized with the SN65LV1023. The data input bits D0-D8 on the serializer are in a fixed alternating 1/0 except for the pulse train input sync signal on D9. I will force synchronization using the sync pins at power-up. In the system I am sending the serializer output through a fiber connection using SFP modules. The output of the SFP module is AC coupled and since the data is not DC balanced, can I assume there will be a problem with the SNLV1224 inputs as far as meeting the common mode input specification? Can this be solved by choice of termination with PU/PD? If the pattern is 101010101x can I count on a static DC imbalance and just put high value PD's on either side of the differential 100 termination to get the CMV down to 0V?
Any input would be appreciated.
