ADG3257

Is there any 2:1/ 4:1 Mux/Bus switch available for the below mentioned requirements.
Inputs range:
* Generating 1x16MHz at 5V logic and 1x16MHz at 3.3V logic and I want to select any one of the clock.
* Input voltage level: 3.3V and 5V
* Input Logic: LVCMOS and CMOS/TTL
Output requirements:
* Output: 5V(CMOS/TTL) or 3.3V (LVCMOS)
Please let me know whether ADG3257 part will be suitable for this requirement.
Thank you.

  • Hi Christian,

    Thank you for your reply.

    There is a update on my requirements. We have finalized two different approaches. 

    Approach1:
    Inputs:
    * Input frequency: 2x16MHz at 3.3V LVCMOS logic and 1x16MHz at 5V CMOS logic.
    * Input voltage level: 3.3V and 5V 
    * Input Logic: LVCMOS and CMOS/TTL
    Output requirements:
    * Output: has to support both 5V(CMOS/TTL) & 3.3V (LVCMOS)
    Approach2:
    Inputs:
    * Input frequency: 2x16MHz at 3.3V LVCMOS logic.
    * Input voltage level: 3.3V only
    * Input Logic: LVCMOS 
    Output requirements:
    * Output: has to support both 5V(CMOS/TTL) & 3.3V (LVCMOS)
    Can you please suggest the suitable part number?

    Hi Keerthana,

    What is your specific application for the mentioned requirements? Do you need to voltage translate the input to a certain level at the output? Or, you only need the signals to pass through the switch?

    Best regards,
    Christian
