Other Parts Discussed in Thread: SN65LVDS4, DS90LV001, DS90LV004, DS10BR150
Hello,
 
I'm serching Interface device of LVDS-25 of Virtex 6.
Please see the attached pdf as connection.
 
I think that LVDS-25 need 2.5V of Vcc supply.
And in this system, ESD voltage is necesary.
 
Could you please kindly let me know the good interface device for LVDS-25 ?
I can't find Vcc=2.5V device for LVDS-25 interface.
 
Best Regards,
Ryuji Asaka

    Hi Ryuji,

    Take a look at the SN65LVDS4 , it is a 2.5V LVDS receiver. Is the system you are designing a synchronous system? Is this the purpose of the LVDS part that is interfacing with the LVDS-25? Does it have to be single ended or will differential signalling work?

    Regards,

    Mike

    Hello Mike san,
     
    Thank you for the information.
    I checked information to my customer, thus 3.3V Vcc is OK.
    LVDS need differential input/differential output.
    Please see the attached file as updated connection.
