ADC3443: SYSREFM LVDS inputs, do they have internal 100 ohm resistors?

Part Number: ADC3443

SYSREFM LVDS inputs needs an external termination? I’m 90% sure that it doesn’t as there is no mention of termination in the D/Sheet or in the reference design. I was just wondering if you can confirm that the 100R LVDS termination is internal to the ADC.  

  • Hi Ajayt,

    The ADC SYSREF inputs do not require 100 ohm termination. If you will be using an LVDS driver for the SYSREF input, then, yes, 100 ohm termination will be required due to LVDS requirements.

    Best Regards,
