parallel lvds outputs

I need to drive an IR led driver at high speed. the driver has multiple channels (6) an all are paralleled in a single enable input. The driver's enable input is lvds but the input capacitance per pi...

Hello,

Yes, the delay is a lot.. and it will be an issue at 20Mhz. I have read the IC driver spec and they specify 760pF per input. A recommended configuration for the IC driver is to use all channels in parallel I can use a TTL instead LVDS still evaluating this so, that is why I was thinking on use paralleled outputs.

Thanks for the info
