Part Number: THS7347 Customer was using THS7347 as the mux for VGA1 and VGA2, without any issues for the resolution XGA and WXGA.
They plan to use THS7347 as the mux for 1080p and WUXGA in the future.
They want to know (1) if THS7347 is capable? and…
Part Number: THS7347 Dear Sirs,
My customer asked us about how to deal of unused pins for THS7347.
He does't use INPUT B and MONITOR OUT.
So, please let me know how to handle the following unused pin.
Pin-No.7～11 and Pin-No.39～46
Best Regards…
Hi Yue,
To better understand the problem:
1. Would it be possible for you to point out in the color image as to where exactly you see the stripes appearing when the blue background is displayed?
2. Also, would it be possible for you to attach a clearer…
Hi Hasan,
ehm, I would like to disagree a bit. The THS7347 is a mixed analog digital chip and has analog and digital ground pins (DGND and AGND). Drawing a proper layout might not be trivial at all. A good datasheet should contain information of how…
Hi Chang,
After giving soem thoughts, would it be possible to change the connector cable connected from EVM1 to EVM2? Also, is it possible to look up the EVM1 ch 1 monitor output & EVM2 ch 1 monitor output on an oscilloscope? The outputs on both the…
Other Parts Discussed in Thread: THS7347 Hi Team
we have use THS7347 on project. We want pass VESA SPEC for video outout Voltage.
Did we must setting DC Coupled mode ? output low is 0V.
Hi Kerr,
The THS7347 is supported in the High Speed Amplifiers forum. You can re-post your question there so one of my colleagues will be able to help you.

Other Parts Discussed in Thread: THS7347 HI Sir
1 : could you provide THS7347 layout guide ?
2 : For input Ac coupling cap , Spec use 0.1uF and 2.2uF, but EVM use 1uF for GRB signal .
what different between SPEC and EVM setting? what Affect for…

Hello Chang,
The THS7347 EVM has been designed for use with 75-ohm inputs. If your system requires a 75-ohm input impedance, then you would need the 75ohm to GND at the H-Sync and V-Sync inputs as used in the EVM. This is required so that there is no…
