DM368 Rev1.2 Silicon Errata

Hiroshi Kimizuka

Hi,

My customer would like to clarify of the Advisory 1.2.3 and 1.2.5 in DM368.

1) For Advisory 1.2.3, is there any quantative metrics in the degraded image quality due to this intra prediction problem ?

2) For Advisory 1.2.5, which temperature does it make this failure happened, high side or low side ?

I think the guard band in high temperature side is squeezed, because the Tc is degraded to 65c from 85c. Is my understanding correct ?

Thanks and Best Regards,

For question number 2) consider the failure can happen just as equal whether high or low side. I'm include others to help with the answer to #1

Hi Marcus,

Thank you for your reply.

For # 1), I'm waiting for your feedback.

For # 2), is there any quantative data to be failed in higher and lower temerature ?

Thanks and Best Regards,

1) I'm consulting with the expert and will get back with you

2) During bench test we could reproduce often as a result of lowering the temperature from 40c to -2C
