Thank you.

You do not mean "Polyphase Clock Sync" but "Symbol Synchronizer"? Is this part 
of the standard blocks in GRC?
Because in my 3.7.11 versions (current Ubuntu) I do not find it.

I do not must use the M&M TED.

All I need to do is asynchronously detect a stream of bits like this:

Maybe there is a better way to do this?
Important key figure is fast settling/lock time because I cannot afford loosing 
bits (one burst is only 100 or so bits long).
