KCU105 - UG917 (v1.2.1), MGT Quad 226 refclk description and Table 1-10 do not correlate

Description

GTH Transceivers Quad 226 is described on page 38 of UG917 (v1.2.1).

In this description, MGTREFCLK0 is described as being the FMC clocks, while MGTREFCLK1 is described as being the SMA clocks:

"MGTREFCLK0 - FMC_LPC_GBTCLK0_M2C_C_P / _N

MGTREFCLK1 - SMA_MGT_REFCLK_P / _N SMA GTH clock input"

Is this correct?

Solution

The description of Quad 226 on page 38 is incorrect.

In this description the refclk information is swapped.

Table 1-10 of UG917 (v1.2.1) has the correct information.

"MGTREFCLK0 - SMA_MGT_REFCLK_P/N SMA GTH clock input

MGTREFCLK1 - FMC_LPC_GBTCLK0_M2C_C_P/N"

This is corrected in UG917 (v1.3).
