They offer 3 dB large signal bandwidth of over 480 MHz along with a slew rate in excess of INPUT 4.5 2.5 1500 V/s. With better than 80 dB of all hostile crosstalk and 2.0 4.0 95 dB OFF isolation, they are suited for many high speed appli- 1.5 3.5 cations. The differential gain and differential phase error of 0.05% 1.0 3.0 and 0.05 , along with 0.1 dB flatness to 85 MHz, make the AD8186 and AD8187 ideal for professional and component video 0.5 OUTPUT 2.5 multiplexing. They offer 4 ns switching time, making them an 0 2.0 excellent choice for switching video signals while consuming less 0.5 1.5 than 20 mA on a single 5 V supply (100 mW). Both devices have a 1.0 1.0 high speed disable feature that sets the outputs into a high 15 20 05 10 25 impedance state. This allows the building of larger input arrays TIME (ns) while minimizing OFF channel output loading. The devices are Figure 1. AD8187 Video Amplitude Pulse offered in a 24-lead TSSOP package.
