Hi Team,
Question regarding the SM320C32 (5V) DSP electrical operation.
If the external data bus was rather long (6") and fans out to several components (5x) could the signal reflections from data bus write cycles cause any upset with the DSP?
We are running tests and have found that a certain sequence of writes to an external parallel DAC on the data bus results in the DSP apparently hanging up. One thought is the data bus reflections are generating currents in the DSP substrate.
Has TI experienced this type of fault before ? or is it even plausible.
Thank you,
Jared
