The second diagram is not clear enough to enable me to make out the input settings for the SAA7350 and thus the output settings for the SM5840A but this can be worked around. How have you connected the SM5840A to the PCM63's and can you float the MCK, MDT and MLE pins?
 
On page 15 of the SM5840A is all the relevant information. All you need to do is load two bytes at start-up.
Byte 1 is 1000 0000.
Byte 2 is 1101 0011
These settings will work but it might be an idea to make some of the bits selectable either via switch or jumpers.
You will also have to disconnect the data lines from the onboard microcontroller, MDT, /MLE and MCK and connect your own microcontroller.
