1) Regarding the AD1974, the data sheet mentions that 16 channels are supported. However, the example of daisy chaining the AD1974 only shows two addition devices - is it in fact possible to connect 4 x AD1974 together?
2) If 4 devices are supported, how are they connected, are there any example schematics etc?
3) Can a single 12.288mhz oscillator drive all the clocks directly and support 48khz sampling rate for all 12-16 channels?
4) Finally, the data sheet shows the connection with a Sharc with ABCLK going to both TxCLK and RxCLK. Why is does it need to go to TxCLK?
This began as a question about the SHARC, and the most recent response appears to have switched over to Blackfin for the processor. I'll try to address them both. In the old SHARC processors (at least…
I have sent a corrected, full-page PDF of the schematic to you in a private discussion. Please let me know if you have any other questions.
I would like to know how to connect daisy-chain 16 channels You could send me help please
thanks in advance
I too am connecting 4 of these ADCs in Daisy chain mode. The high-res schematic with readable netnames would very helpful in confirming if I am connecting it correctly.
