Differential signal Power divider

Hi Tsingyang,

Few questions:

1. Power Supply Requirement

2. Voltage Ranges

3. Input Specifications, etc.

What will be your intended application?

Regards.

Hi Jinol

1.My power supply is 5V and 3.3V

2.My design Voltage Ranges are 1.2V to 5V

3,My input signal is FSK and it range from 0.1v to 1.1V ,then this FSK will as a input of AGC AD8338.

4.Finally the output of AD8338 will as a input of AD8131,the front of the picture 1 is AD8338 what I omit here

                                                                  Picture 1

                                                             Picture 2

picture 1 is original design,picture 2 is what  I want to add.

Hi Jinol

Do you have some ideas about my questions?Thanks a lot!

Best Regards

Hi tsingyang,

Just to be clear, what do you want to implement? Is it

FSK (input) >> AD8338 >> AD8138 (2 channels) >> AD9224 (ADC)

Is it correct?

Regards.

Hi Jinol

My implements is just as bellow

FSK(input)>>AD8338>>AD9224(2 channels ).I intent to have 2 channels signal to drive two AD9224,but I only have  one AD8338,the AD8138 is optional.What I want to do is that change one channel signal two channels signal.

Thanks a lot

Hi Tsinyang,

One more question, what will be your preferred application? AC or DC-coupled?

Hi Jinol

My application is AC-coupled.

Thanks a lot!

Hi Tsingyang,

I would recommend a multiplexer, a 2:1 MUX to be specific. You can find them in this link Selection Table for All Analog Switches and Multiplexers | Parametric Search | Analog Devices. For a quick suggestion, try looking at ADG824, ADG854, and ADG736, and see if one of these fits your requirement.
