We are working with a local customer that is planning on using the ADSP-BF561 in an application which will process multiple channels of sensor data.
Within the application, they will utilize 8 AD7622 (parallel) ADCs to convert the post-filtered analog sensor data into something usable by the DSP. Specifically, the ADCs (8) will interface to a digital mux, which will then connect to the ADSP-BF561 via 1 of the 2 onboard PPI (parallel) interfaces.
They had a few questions that I was hoping you could help me with:
They are looking for CAD/Scematic Symbol files for the following:
BF561SBBZ600 (297 ball PBGA)
BF561SKBCZ-6V (256 ball CSPBGA)
I started looking here:
And found the footprint for the 297 ball:
and for the 256 ball:
But I could not find the schematic symbols (they mentioned .BXL files).
Can we provide a symbol to the customer for these packages?
They wanted to know if in addition to the following AppNote: http://www.analog.com/static/imported-files/application_notes/AN-813.pdf
If we can provide any other existing examples/AppNotes that address interface multiple ADCs to a Blackfin via PPI.
They asked if there were any suggestions/concerns the factory may have related to this configuration and if you could recommend a specific mux that should be used in this application.
Thanks in advance for your help.
