Part Number: CDCLVP1216

Hello,

I would like you to confirm about following configuration is acceptable or not.

* Connect output of CDCLVP1216(LVPECL out) to two LVPECL input device also LVDS input device.

This means fanout number is three (two LVPECL and one LVDS input device.).

My concern is that multiple LVPECL can NOT be connected to CDCLVP1216 due to output current capablity.

(Power supply for CDCLVP1216 is 2.5V.)

However, I'm not sure output current capability of CDCLVP1216, could you please give me your opinion about above configuration ?

Best Regards,

  • Hello,

    Would you have a schematic to share? If you do not want to post the schematic on the forum, you could send me the schematic in a private message.

    If I understand your question correctly, you want to drive three receiver channels with one transmitter? It is not recommended to drive multiple clock receivers from one transmitter. TI recommends one clock buffer to one receiver. As you stated, the power will split when driving multiple receivers.

    Kind regards,
    Lane
