Hi Per,
Thanks.
I've already noted to myself to make sure the input capacitance (0.9 pF) and input resistance (28 kohm) are added to the LMH7322 datasheet on the next revision.

Hello,
To answer your questions:
1. What is the output of LM9833 and where to see it?
Response : The 16 bit ADC data output(s) of the LM9833 are on pins D0 (LSB) -D15 (MSB).
2. Is this IC pre programmed if not how to use this IC?
Response…
Hi PengYan,
Thanks for the schematic.
I understand that you like to maximize the voltage across the photodiode for faster response and for more headroom. However, the LMH6629 output voltage cannot swing down to 0.5V (it is limited to 0.80 V min and…
Hi kato-san,
I think what you are looking for is an analog VGA (Variable Gain Amplifier) such as the THS7530 (300MHz bandwidth), etc.
Here is a parametric list of these devices:

Hello,
You can refer to the LM8261 (single version of the LM8262) for the output voltage vs. output current plots you are looking for (Figures 24 through Figure 26).
The two devices will be identical from that regard.

Hello,
Yes the OPA3875 (triple) and OPA875 (single) can also perform the Muxing of CVBS video. For a quad configuration, you need more devices, of courses.

Hello Alex,
I agree with you that would be good to have some plots to show the overload recovery. The LMH6639 is based on the LMH6642 with some minor changes (shutdown was added, output current improved, slew rate improved, etc.).
So, you can see…
