No no from Datasheet said the Detector from MX614 diffent than detector from 
TCM.Also /RDY timing didn't appears in TCM.
MX614 tolerants againts the baudrate drift,the TCM must precise the baudrate
i.e 1200 bps or 2400bps depends on crystal with TCM.

I'm saying,Didn't had MX614P and imposibble to bought the MX614P.
Did you had info how's to get sample the MX614P?
Here the MX614P was 30US$/piece and TCM only 15US$/piece.
I had 6 chips TCM3105NL.
