** (Xilinx Answer 59294) details a possible power up issue for 7 series GT transceivers. A work-around will be included in the CPRI core in the 2014.3 release.

To avoid this issue please ensure that a reference clock is present for the transceiver when the device is powered up at line rates of 6144Mbps and below.


Known and Resolved Issues

The following table provides known issues for the LogiCORE IP CPRI core, starting with v7.0, initially released in Vivado 2013.1.

Note: The "Version Found" column lists the version the problem was first discovered.

The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
