Part Number: AFE7901 Tool/software: Hi, I'm a little bit confused. The datasheet says that the impedance of the TX port is a differential 100 ohm, but in some application notes and the layout I can see the impedance is a differential of 50 ohm. In the…
Part Number: AFE7901 Other Parts Discussed in Thread: AFE7900 Tool/software: Hi, I'm willing to use the AFE from 400 - 6000MHz with the same port so I'm dealing with wideband impedance matching. I'm looking for a measurement \ documentation of the input…
Hi Maor,
The reason for this is because as you increase the input fundamental power, at some point the noise floor of the clock will appear in your FFT.

Hi Aman,
Yes, it is still like that. It is good that you see it as well. It seems there are some hidden signal processing steps which are not clear for us.

Part Number: AFE7901 Tool/software: Hi Team,
if customer will use ADC (Tx) in AFE7901 and leave the DAC pins (Rx) unused then will this add any noise into the system?
Part Number: AFE7901 Other Parts Discussed in Thread: AFE7903 Hello Expert,
my customer is currently interested in AFE7901 and AFE7903. they want to use this RF sampling chip as a normal high speed ADC. Regarding the application of chips, they have the…
Part Number: AFE7901 Tool/software: Team,
is it possible to sample 4 channels with 2 x 125 MHz (2 DDCs) each?
The datasheet mentions IBW of 400 MHz. 2 x 125 MHz = 250 MHz < 400 MHz Can you confirm this?
Best regards
Part Number: AFE7901 Team,
What does the “Min Full scale input power, at device pins” on page 22 refer to? Does it refer to the power at 100 ohms, i.e. approx. 0.9Vpp? As a full-scale value, I would have expected a voltage value. Is only the…
