UXGA resolution video MUX

15 June 2005 Analogue, Mixed Signal, LSI

The LT6555 is claimed to be the industry's fastest 2:1 multiplexing triple video amplifier. Achieving beyond UXGA quality resolution, this Linear Technologies part is ideally suited for use in high-resolution video with multiple inputs or outputs. The 2:1 input multiplexers simplify the selection of two video signals while the internal fixed-gain of two amplifiers eliminates external gain setting resistors when driving 75 Ω back-terminated cables. Bandwidth of 650 MHz and a very high 2200 V/μs slew rate allows it to process large input signals. AC performance is enhanced with quick 6,5 ns settling time. Also suited for use as a front end receiver or an output cable driver, the LT6555 can switch RGB signals in UXGA LCD projectors and monitors, signal routing in professional video equipment and hifi multi-input video switching applications. Offered in 4 x 4 mm QFN and 24-pin SSOP packages, it operates on dual or single supplies from 4,5 V to 12 V.
