we are using Cyclone 10 (10CX105YF780E6G) and
we have to implement an LVDS Receiver for 33 rx_in channels with only one rx_inclk at a data rate of 900Mbps.
So, we need at least 2 I/O banks and 2 LVDS SERDES instances.
How can we use the same rx_inclk for several LVDS SERDES instances with their I/O PLLs?
Can we use the Global clock network for the reference clock to the I/O PLLs?
The PLL inclock frequency of our design is 450MHz for a data rate of 900Mbps.
Reducing the LVDS Receiver SERDES to 8 rx_in channels with the PLL reference clock on the same bank as the data channels, the compilation is successful.
With more than 8 rx_in channels we want to use the PLL reference clock from another bank. Is this possible?
I am sorry to tell you that that is not possible because IOs on each banks work independently. I hope you can work your design around this constraints.
