The DS90C189-Q1's LVDS drivers are compatible with ANSI/TIA/EIA-644-A LVDS receivers. The LVDS drivers can output a power saving low V_OD, or a high V_OD to enable longer trace and cable lengths by configuring the VODSEL pin.

Any unused LVDS outputs that are not powered down due to the MODE0 pin should be externally terminated differentially with a 100 ohm resistor. For example, when driving a timing controller (TCON) that only requires an 8D + C LVDS interface, rather than 8D + 2C, the unused clock line should be terminated near the package of the DS90C189-Q1. For more information regarding the electrical characteristics of the LVDS outputs, refer to the LVDS DC Characteristics and LVDS Switching Specifications.
