LVDS to DIFF_HSUL_12

Hi All,

 

We want to connect LVDS clock oscillator to a HSUL_12 bank pins.

 

How can I convert the LVDS to DIFF_HSUL_12?

 

The motivation is because we using a LPDDR2 connected to a Artix 7, and we want to connect a diff clock to the related bank.

 

Thanks

 

Shay

Re: LVDS to DIFF_HSUL_12

What is your lvds voltage 3v3 / 2v5 / 1v8  ?

 

 

See here  https://www.xilinx.com/support/answers/43989.html

 

You might be able to just use a lvds dif input 

 

 

Basiclay 

 

with a clock , its 'easy' 

   as its constant ,

 

'just' ac couple , external terminate, and possibly use resistors to put the Vcom into the right place with the right swing.
