Texas Instruments Inc. (TI) introduced three high-speed video multiplexers.
The devices are designed to feature wide bandwidth and fast slew rate, which allows the multiplexing of large amounts of data such as high resolution video signals at higher speeds than previous generations, according to TI.
For example, the OPA875 single-channel and OPA3875 three channel 2:1 multiplexers feature a small signal bandwidth of 700 MHz with a slew rate of 3100 V/us, which supports a large signal bandwidth of 425 MHz at 4 Vpp, said TI.
The OPA4872 single-channel 4:1 multiplexer offers a slew rate of 2300 V/us for a bandwidth of 500 MHz at 2 Vpp.
High-speed multiplexers are used to switch between multiple sources in applications such as projectors, monitors and routers. Beyond video, the device can also be used in other high-speed signal multiplexing applications.
In addition to these high-speed capabilities, the devices are touted as using a low glitch switching technique to enable fast and seamless multiplexing of high-speed signals, claims TI.
