The LT1204 is a 4-input video multiplexer designed to drive 75ohm cables and easily expand into larger routing systems. Wide bandwidth, high slew rate and low differential gain and phase make the LT1204 ideal for broadcast quality signal routing. Channel separation and disable isolation are greater than 90dB up to 10MHz. The channel-to-channel output switching transient is only 40mVP-P, with a 50ns duration, making the transition imperceptible on high-quality monitors. A unique feature of the LT1204 is its ability to expand into larger routing matrices. This is accomplished by a patent pending circuit that bootstraps the feedback resistors in the disable condition, raising the true output impedance of the circuit. The effect of this feature is to eliminate cable misterminations in large systems.
