ADC3444: ADC3444 : Termination for Digital Output

Nachiketh Karanth

Part Number: ADC3444

Hi Team,

Is any serial or parallel termination required for Digital outputs?

Thanks

Hi Nachiketh,

This ADC has a digital LVDS output interface. LVDS needs a 100ohm differential termination at the receive end.

Depending on the FPGA used in your system, this option might be available internal to the FPGA.

If not, then please provide the termination externally near the FPGA receiver pins.

Regards,

Rob

Hi Rob,

Is there any package pin delay for this IC?

Thanks

Hi Nachiketh,

You can use the IBIS model for package parasitics of the IC.

This is located on the TI webpage for this device.

Scroll down and click on the "design tools & simulation" tab.

Regards,

Rob
