DS90CP22: Finding crosspoint switch

Part Number: DS90CP22
Other Parts Discussed in Thread: DS25CP102, TMUX121, TMUXHS4446

Tool/software:

Dear Technical Support Team,

I'm finding following crosspoint switch

・Differential signal (0.6V-1.2V, terminated at 1.2V/50Ω pull-up on the receiving IC)

・Signal bandwidth: approximately 1Gbps

・Two outputs per one input (1:2 distribution)

I think DS90CP22 and DS25CP102 seems to be good for them.

If you have any recommendation for these requeiment, please let me know.

Best Regards,

ttd

    Hi TTD,

    Will the TMUX121 work for you? This is a 2 channel 2:1 switch with 3GHz bandwidth that can pass differential signals.

    Best,

    Hi Katy,

    Thank you for your reply. Interface is CML. 1.2V/50Ω pull-up on the receiver, so I need to no internal pullup crosspooint switch.

    Is there good device for required spec?  

    LVDS, M-LVDS & PECL ICs product selection | TI.com

    ・Differential signal (0.6V-1.2V, terminated at 1.2V/50Ω pull-up on the receiving IC) ⇒hope no internal pullup

    ・Signal bandwidth: approximately 1Gbps(CML)

    ・Two outputs per one input (1:2 distribution) ⇒ I think 2x2 crosspoint switch can select 1:2

    Best Regards,

    Hi TTD,

    TMUXHS4446 might be a good option for you - it is a 10Gbps crossbar switch that supports differential signaling with a common mode voltage from 0 to 1.8V. It has a 4:6 configuration, so could be used as a 1:2 if desired.

    For non-crosspoint switch suggestions for LVDS, you can check out our FAQ here!

    Best,
