No, not really. I think SDMAC 04 was really over-rated in it's ability to solve timing problems primarily caused by Ramsey's over-dependence on CLK90. I think C= was also looking for a way fix timing problems with the A3000T (they really messed up the clock circuit for the A3000T).
SDMAC 04 chips are VERY RARE and VERY EXPENSIVE so I would look for other solutions before trying to find one.
