Hi,

Please refer the ALTLVDS user guide section 1.3.2: https://www.intel.com/content/www/us/en/docs/programmable/683062/17-1/lvds-serdes-transmitter-receiv...

 

In external PLL mode rx_coreclock can be used in the fabric logic to further process the data. In this mode, rx_coreclock is same as the rx_syncclock which is an input to the ALTLVDS_RX.

rx_syncclock is used to receive the parallel data.

Hi,

The ALTLVDS IP has rx_coreclock signal. You can connect the fabric clock to it.
