ADC12D1600QML-SP: Coupling effects

Gregory Duperon

Part Number: ADC12D1600QML-SP
Other Parts Discussed in Thread: ADC12D1600

I am looking for data or information on the coupling effects between VIN (I +/-) and VIN (Q +/-) Pins.

My customer is planning to drive the I and Q with different signal types and wanted to know the coupling levels.

Hi Greg,

I assuming you mean channel to channel isolation. I can test this in the lab for you, but I need a bit more information.

What sample rate and analog input frequency range is being used for the application.

Any other specific setup featured that will be used or reg writes to the ADC.

Regards,

Rob

Rob,

Sample rate = 1600MSPS

Analog Frequency Range is 880 – 1520MHz

Mode is Non-LSPSM 1600 MSPS

Thanks.

Hi Greg,

Thanks for the information.

I will get back to you with some isolation data over that frequency range.

Regards,

Rob

Hi Greg,

I have the measurements for the ADC12D1600. See attached.

However, i would have to order an 1600QML EVM if this is needed specifically.

Also, there is some of this data already in the datasheet.

Thx,

Rob
