Hi,everyone, I'm currently developing on a ArriaII EVM together with an HSMC daughter card (TI's ADS62p29EVM through HSMC-ADC-bridge adapter). I need to use DDR LVDS for interfacing the cards. ...

hi,FvM,

Thank you for your reply.

I'm so confused about the altlvds_rx and altDDIO module.

Implementing a DDR signal, 1:2 SERDES and DDIO module are both the same function?

however, DDIO do not have a internal PLL.Do I really need one ? or either is ok?

I have uploaded the ADC's waveform.Can I use the clkout_P or clkout_M directly with out pll?

thanks a lot.
