High-speed triple 2-to-1 multiplexers

10 September 2002 Telecoms, Datacoms, Wireless, IoT

Analog Devices' AD8183 (G=1) and AD8185 (G=2), triple 2-to-1 multiplexers offer -3 dB full signal bandwidth up to 360 MHz and slew rate in excess of 1000 V/µs.

Low all-hostile-crosstalk of -72 dB, 100 dB of isolation, differential gain and differential phase error of 0,01% and 0,02°, 0,1 dB flatness to 90 MHz, and 15 ns switching time make these muxes an excellent choice for professional video and LCD multiplexing. A high-speed disable feature that can set the output into a high-impedance state allows the building of larger input arrays while minimising OFF channel output loading.

Key features: fully buffered inputs and outputs; fast channel-to-channel switching (15 ns); high speed (bandwidth, slew rate, settling time); low power (25 mA).

Some applications are for pixel switching for 'picture-in-picture', switching RGB in LCD and plasma displays, and RGB video switchers and routers.
