I've designed and now I'm debugging DAQ with ADC34j22 (totally 4 ADCs chips=16 input channels) - I can work with normal mode LMFS=4421( 4 lines, 4 converters,2 octets/frames, 1 sample/frame) and all data are correct with 50 MHz.
But I cannot made that ADCs and my receivers working correctly for mode LMFS=2441 ( 2 lines, 4 convertes,4 octets/frame, 1 sample/frame).
I'm using instructions from datasheet for ADC34J2x(pages 53 and 58) : configure register (addr 2Bh) with 01h and register (addr 30h) with 11h - results very strange... and with many effort no any positive results...
but I've found that on datasheet for ADC34J4x(pages 54 and 60) wrote that for register (addr 30h) should programmed 03h ?
And I've started to think that many those "11h" on datasheet ADC34j2x are really means "11b" . On table 33 of that register 30h description those 11 not cleary described (or it's 11h or 11b).
Some body really used those ADC on that mode 2441 ? I strongly need to use that mode because my design was based on that mode -- now half of channel not available for measure...
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to David Guidry:
I don't understand, if you agreed that I'm correct, why on TI web site still that old datasheet with INCORRECT information presented. By that error your ingineers created a lot of problems and don't worry to repair your errors ? My boss was ready to charge TI for our 3 months delay -- we lost not only a lot of time, but also possibility to present our system to customer with best parameter -- just half channels was working.
But then he decided not to do. Are you waiting that somebody other will do this ?
I'm very surprised by low qulification your engineers. And I received bad words from my boss about my decision to work with TI ADCs. Previously we used just AD ADCs. I still think that those TI ADCs are really good devices, but unattention in description about using chips can destroy any good things...
I'm very disappointed.
