Known Issues

- TXPOWERDOWN/RXPOWERDOWN issue - The core does not assert a reset after assertion/de-assertion of


Refer CR471776 : For GTP

Refer CR471777 : For GTX

The assertion of RXPOWERDOWN from "00" to "11" causes the RXRECCLK to flatline. It is recommended

to pulse the RXCDRRESET. This a safe measure to clear the registers (including resetting the

pointers of the elastic buffer) and of starting the CDR in a clean state once the RXRECCLK starts

to run again
