Note
1)LVDS input pin connection
When LVDS line is not drived from the previous device, the line is pulled up to 3.3V internally in THC63LVD1027.
This can cause violation of absolute maximum ratings to the previous LVDS Tx device whose operating condition is
lower voltage power supply than 3.3V. This phenomenon may happen at power on phase of the whole system includ-
ing THC63LVD1027. One solution for this problem is PD=L control during no LVDS input period because pull-up
resistors are cut off at power down state.

2)Power On Sequence
Don’t input RCLK#+/- before THC63LVD1027 is on in order to keep absolute maximum ratings.
