TCI6638K2K: Errata Clarification:

KALIDOSS RAMAKRISHNAN
Prodigy 50 points

Part Number: TCI6638K2K

  1. In “Literature Number: SPRZ401F”, Table 4. Silicon Revision, 3.1 is mentioned as the applicable revision. But in detailed explanation, Revision(s) Affected: 3.1 is not mentioned. Is it a typo and still applicable for 3.1?

  1. In Usage Note 7, in workaround, it is mentioned that,

    • On PG 1.0 silicon, TI recommends that both AVS rails must be tied together.
    • On PG 1.1 silicon, these two rails are tied together internally

So, we assume, from 1.1 on wards (even for 2.0,3.0 & 3.1), it’s taken care internally. Please confirm.

    This is what the Silicon Errata document suggests, so I think your understanding is correct. Just in case I am looping the design team to elaborate if necessary.
