Part Number: CDCI6214

Hi Expert,

The customer set Y4 to LVDS100MHz and checked the waveform on the customer's board.
The amplitude is about 0.7V as shown below.

Customers use 0.1μF ceramic capacitor on Y4P and Y4N lines for AC coupled.

The datasheet is descripted about maximum amplitude(DC coupled)  0.45V. Could you tell us why this value is exceeded?
