Missing data in AM335x Datasheet (DDR3 Routing Specification)

Kika
Intellectual 420 points 
Hello,

We need confirmation about the AM3359 datasheet's missing data and a typo.

No 1.
Regarding the DDR3 Routing Specification,
There is a missing data in the pg 170: "Table 5-59. CK and ADDR_CTRL Routing Specification".
The MAX value for "Rcp" (No.19) is not mentioned properly.

Can we assume the MAX value as Zo + 1?

No.2
Regarding the DDR3 Electrical Characteristics,
pg84 "Table 3-7. DC Electrical Characteristics" mentions VIL(Low-level input voltage)
MAX value as "VDDS_DDR - 0.1", is this a TYPO?
we believe that value would be "DDR_VREF - 0.1" instead.

Can we assume the VIL MAX value as DDR_VREF - 0.1?


Regards.

    Thanks for bringing these data sheet issues to our attention.
    

    No 1.  Your assumption is correct.  I will submit this update to the next revision of the data sheet.
    

    No 2. You are correct VDDS_DDR - 0.1 should be DDR_VREF - 0.1.  You are the second person to highlight this issue and the update has already been submitted to the next revision of the data sheet.
    

    Regards,
    Paul
