The LT1675 is a high-speed RGB multiplexer designed for pixel switching and fast workstation graphics. Included on-chip are three SPDT switches and three current feedback amplifiers. The current feedback amplifiers drive double-terminated 50? or 75? cables and are configured for a fixed gain of 2, eliminating six external gain setting resistors. The SPDT switches are designed to be break-before-make to minimize unwanted signals coupling to the input. The LT1675-1 is a single version with two inputs, a single output and is ideal for a single channel application such as video sync.
