66AK2H14: Swapping data lines in DDR3 Interface

Madhu Sharma

Part Number: 66AK2H14

Hi,

In 66AK2H14 devices, as per the user guides, data lines can be swapped within a byte.

I would like to know whether any data line can be connected to any other line (within a byte ). Because, in some processors, normally first bit of each byte is not swapped with any other.

Thanks & Regards,

Madhu

Madhu,

As documented, any data bit within a data byte may be swapped. The DDR3 PHY implemented in 66AK2H14 does not have any restriction on the prime bit for leveling.
