Can LVDS be accomplished on simpler switches?

Hi Emrys san.

Thank you for the reply.

Sorry, I don't have the detailed information,
so please tell me the words of caution when we use the bus SW as the LVDS SW.

※I think my customer would like to make an architectonic like a SN65LVDS122 by a Bus SW,
if you have devices that can achieve the device of TI and architectonic, please tell me.

Best Regards,

Sho-san,

The problem with using CB3Q for this application is in the voltage range of the part. It's my understanding that the LVDS parts are designed to operate with differential signals (ie one positive and one negative signal) which allows for higher data rates. The CB3Q switches are designed to operate from -0.5 V to 7 V with single-sided signals. If the signals can be kept inside that operating range, I don't see why it wouldn't work... but I would recommend using the parts designed for LVDS.

Since I am not an expert on the LVDS parts, I am going to split this thread over to the high speed interface forum for additional support.

Thanks Sho-san. The link was supposed to just go back to the original thread in the Logic forum. I don't know why it isn't working!
