Part Number: DS25BR110
Hi您好，
Hi,
The differential input signal amplitude of the DS25BR110 is below the specified threshold of 100 mV. In actual testing, the yellow waveform represents the input signal, yet the output remains normal. How can this be explained? How can it be determined whether the input signal meets the device's requirements? Thank you!
This is a function of the equalizer, which you have set to the highest setting. At this setting, the equalizer boosts the signal by about 16dB at 1.56GHz. If you pull both the EQ pins low, you will see that the device doesn't read those 50mV signals. You can read more about it here: https://www.ti.com/lit/an/snla115a/snla115a.pdf?ts=1769582252114
