Steve,
Your I2C transaction looks to be corrupted.
I have transformed your 'scope image (below).
SDA should rise between transactions. It doesn't.
"ACK" looks to come in the middle of a transaction (should come at the end.

Am guessing a power-up problem. Perhaps a slow rise in the DC supply?
In any case, looks like SI5351A sees a I2C framing error.
