Notes for the table :

Warning

Caution - DO NOT CONNECT the GT95014 DIO Single Ended Interface Board to User connector J4 if the LVDS clock is enabled.  The LVDS_N signal will get shorted to ground and device damage may result.  Use the GT95015 DIO Differential Interface Board for all J4 functions if the LVDS clock is required.
