Hi all
According to the datasheet this IC should have an LVDS output with a differential amplitude of 350mV.
Onn my setup in the lab I measure a differential Amplitude of around 730mV which is obviously too much.
I terminated the signal with 100Ohm at the FPGA side as written in the Datasheet.
Below is a oscilloscope image of the LVDS signal.
Could it be due to the supply voltage and scale with the input?
Something like: 3.3V supply => 350mVpp
5V supply => ca. 720mVpp
Has anyone an idea about this behavior?
Thx in advance,
Jonas
