LT1675-1 - 250MHz, Triple And Single RGB Multiplexer With Amplifiers

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 Ohm or 75 Ohm 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.
The key to the LT1675 fast switching speed is Linear Technology's proprietary high speed bipolar process. This MUX CAN toggle between sources in excess of 100MHz, has a slew rate over 1000V/s and has a -3dB bandwidth of 250MHz. Power supply requirements are 4V to 6V and power dissipation is only 300mW on 5V, or 100mW for the LT1675-1. The expandable feature uses the disable pin to reduce the power dissipation to near 0mW in the off parts.
Unlike competitive solutions that are in bulky high pin count packages, the LT1675 is in a 16-lead narrow body SSOP. This small footprint, the size of an SO-8, results in a very clean high performance solution. The LT1675-1 is available in the tiny MSOP and the SO-8.
