LT1675/LT1675-1 250MHz, Triple and Single RGB Multiplexer with Amplifiers Features - 100MHz Pixel Switching - - 3d B Bandwidth: 250MHz - Channel Switching Time: 2.5ns - Expandable to Larger Arrays - Drives Cables Directly - High Slew Rate: 1100V/µs - Low Switching Transient: 50m V - Shutdown Supply Current: 100µA - Output Short-Circuit Protected - Available in Small 16-Pin SSOP Package U APPLICATIO S - RGB Switching - Workstation Graphics - Pixel Switching - Coaxial Cable Drivers - High Speed Signal Processing DESCRIPTIO The LT®1675 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 50Ω or 75Ω 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/µs and has a - 3d B bandwidth of 250MHz. Power supply requirements are ±4V to ±6V and power dissipation is only 300m W on ±5V, or 100m W for the LT1675-1. The expandable feature uses the disable pin to reduce the power dissipation to near 0m W in the off parts. Unlike petitive 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. , LTC and LT are registered trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners.
