Currently using DM368. In order to perform HD video encoding, need to send a 74.25 MHz clock to VENC. In order to achieve this, customer configuring the PLLs to get a 74.24 MHz clock on pll2 sysclk 5, but this means the ARM is a bit overclocked at 445.44 MHz (~3% over the DM368's rated 432 MHz). Most of the DM368s we get are fine with this, but some percentage (10-20%?) don't operate correctly.
Does TI do any qualification of chips prior to shipment as to which ones may be able to sustain a bit of overclocking? Is there any way to source these? At the moment, we have no other way to source the necessary clock, so overclocking seems to be required
