PURPOSE: A full/dual base camera link receiver is provided to implement a frame grabber which has two functions of full and dual base with minimum parts thereby comprising an efficient system with various functions on one board. CONSTITUTION: If an LVDS(Low Voltage Differential Signaling) signal which is connected to a connector problem part(pin number 1-7, 14-20) is set as full, a circuit which converts a LVDS driver output into the high impedance is comprised. By an end resistor switching unit, the end resistor is connected to an LVDS terminal. If the LVDS signal is set as a dual base, the end resistor is not connected to the LVDS terminal by the end resistor switching unit.
