DS90UB9702-Q1: Interfacing TI 9702 with TI 971 Serializer

Part Number: DS90UB9702-Q1

Tool/software:

Hi,

I am trying to upgrade a video system using two TI 953 Serializers with a TI 9702 outputting a CMLOut signal to another TI 9702 deserializer to instead use two TI 971 serializers.  I have replaced the 953 with the 971 (the datasheets mention that they are pin for pin compatible) and am unable to establish an FPD-link between the 9702 and the 971.  I have the following questions:
Would it be possible to receive sample code for detecting the 971 from the 9702?

Can you verify that no electrical modifications should be needed when transitioning from a 953 to a 971?
Thanks,

Jeff A.
