TS3DS26227 for LVDS application?

Other Parts Discussed in Thread: TS3DS26227

I have a need to switch between an LVDS (differential voltage of 600 mv with common mode of 600 mv) signal and a CMOS signal level of 3.3 V.  The switching signal ideally is 2.5 V but I can make it what ever it needs to be.



I found the TS3DS26227 and it appears to be exactly the type of part I am searching for but I'm a little nervous that it would have an adverse effect on the LVDS signal.  So was looking to understand if there is something specifically designed for handling LVDS signals.

Thank you,

    You can see on the front page of the datasheet that Low-Voltage Differential Signal (LVDS) routing is one of the stated applications so the TS3DS26227 would be a good fit for your application.   This device also has a 800Mhz bandwidth and supply voltage up to 3.6 V so it will be able to support both signal levels that you are switching; the differential voltage of 600 mv with common mode of 600 mv signal and a CMOS signal level of 3.3 V.  The 2 channel SPDT configuration will also allow you to switch between the LVDS signal and 2 different CMOS level single ended signals if you need.  If you will not be using the the addition channel for another single ended signal, connect the pin to ground through a 50 ohm resistor to reduce the reflections and maintain signal integrity. 

    Thank you,
