Texas Instruments Incorporated (TI) (NYSE: TXN) introduced three high-speed video multiplexers, combining wide bandwidth, high slew rate, fast switching time, and low switching glitch to optimize performance in professional video applications. 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.
The devices feature industry-leading wide bandwidth and fast slew rate, which allows the multiplexing of large amounts of data, such as high resolution professional video signals, at higher speeds than previous generations. 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 4Vpp. The OPA4872 single-channel 4:1 multiplexer offers a slew rate of 2300 V/us for a bandwidth of 500 MHz at 2 Vpp.
In addition to these high speed capabilities the devices use a patented low glitch switching technique to enable fast and seamless multiplexing of high-speed signals.
Availability, Pricing and Support
The OPA875 is available in a SO-8 or the smaller MSOP-8 package, the OPA3875 is available in a SSOP-16 package, and the OPA4872 is in a SO-14 package. Suggested resale pricing in quantities of 1,000 is $1.45 for the OPA875, $2.55 for the OPA3875 and $2.15 for the OPA4872. Samples and evaluation modules (EVMs) are available.
The OPA875, OPA3875 and OPA4872 video multiplexers are part of TI’s complete offering of analog and digital technology to support video designs, including DaVinci(TM) technology. The multiplexers complement TI’s broad portfolio of high-speed amplifiers for the video market. In addition to samples and EVMs, TI provides an array of tools to make it easier to design with TI’s high-speed amplifiers.
