DDC is a routine task and can be done in ASIC, that's right.
However, i doubt that the ASIC can be attached directly to
USB controllers, because you have to handle the data bus,
control bus, controlling the frequency synthesizer.
I think in any case you need a FPGA as glue logic.
If the DDC is done in ASIC, the FPGA can be very small and cheap.

USB 3 offers higher bandwidths than GiE, but GiE can be switched and
allows large distances. So I would prefer GiE if the bandwidth is sufficient.
For higher bandwidths, 10GbE would be an option for future developments.
