MiniDSP 2x4 HD-Drawing a Functional block diagram-Help please.

[djsb]

I have broken MiniDSP 2x4 HD active crossover. As I can't use it, I would like to learn more about how it works as a system. The first step is to create a system block diagram. Here is a list of the main chips that are used (in no particular order)

1/ ADSP-21489

2/ XMOS XEF216-512-TQ128-C20A (marked E01692C20)

3/ AK4626AVQ (codec-ADC/DAC)

4/ TPS65261-1

5/ 45DB321F

6/ CD40106BM (Hex inverting schmitt trigger)

7/ NJM2068 (audio op amps on the 2 inputs and 4 outputs.

There are a few other various diodes and transistors etc scattered around. I'd just like to understand a bit about how the main chips fit together to make the overall system. Can someone help me to understand this? Are there any resources apart from the datasheets (which I will add the links to over the weekend)? Thanks.

Datasheets are the way, really. You could say a large part of a design is the engineers inspiration etc. but but will be 90% informed by the datasheets and thus the capabilities of the devices themselves. You could likely reverse engineer a lot of the design this way. Bear in mind there are programmable devices here.
