Other Parts Discussed in Thread: AM5728, SN75LVCP412A
Hi TI Support,
We have AM5728 evaluation kit (TMDSEVM572X) & further we intend to make our customized board based on EVM schematic. Pertaining to these we will appreciate following queries,
Application background
We have the application of video analytics running continuously in AM5728 processor. We intend to MUX ethernet ports of AM5728 to receive image data from 2 X IP cameras, so both DSP & both ARM cores will be running at HIGH OPP. Apart from that there are some other peripherals in our application which would be running continuously besides mentioned above. Using power estimation spread sheet results in approx 14.5W processor consumption. I also gone through TI application note of thermal considerations.
Queries,
1. Is it practical to dissipate 14W with suitable heat sink & fan keeping junction temperature below 90'C? If yes, can TI provide some directions to achieve this target & possibly advice reference of processor heat sink manufacturer who could help us in this matter?
2. BTW, is it feasible in evaluation board to enable both DSP, both MPU, both IPU, IVA cores at HIGH OPP simultaneously? If feasible, it is advisable from TI to run evaluation board (with heat sink+fan) with portions enabled as mentioned above. Assume ambient to be 25'C.
3. For our custom design purpose, is it OK to use direct SATA port through 0.01uF capacitors without using MUX IC PI2DBS212 & SN75LVCP412A?
4. We don't require PCIe interface, can we remove differential clock IC CDCM9102RHBR & still keep both ethernet ports working on 1Gigabits/s speed from some internal clock of AM5728?
Thanks,
