ALTLVDS_RX

I am using an ALTLVS_RX module in a Cyclone III device. Intel in its datasheet advises against using this module an recommends using BUS LVDS IO standards and logic to implement the function. Why ...

Hi

Can you help me with following?

1. Which part of the datasheet doc you are referring to when you mentioned it is not recommended to use ALTLVDS IP? We can help to check if our interpretation is aligned.

2. When you mentioned that the de-serializer fails to find signals, do you mean the inputs are not toggling or the output is incorrect?

The data rate is limited by the IO specification per device family which we need to adhere to. By using the IP, you will be able to directly utilizing multiple capabilities that come together with it, which you will need to build it with manual logic coding.

Thanks.
