The 4x1 3G/HD/SD-SDI ASI Switcher from Link Electronics is a four-input video switcher that provides a convenient, low-cost way to route high definition and standard definition serial digital signals. This switcher is compatible with 270 Mb/s, 1.5 Gb/s, and 3 Gb/s serial digital interface signals. It can also be used for ASI and SMPTE 310M (19.4 Mb/s) signals, and the reclocking will be automatically be turned off. This switcher automatically equalizes the incoming SDI signal, compensating for greater than 1,000‘ of cable at 270 Mb/s, greater than 250’ of cable at 1.485 Gb/s, and greater than 100’ of cable at 2.97 Gb/s. The signal is then reclocked, with automatic rate detection for all popular data rates. The LEDs on the front panel indicate the data rate of the output video.

This multi-definition SDI 4x1 video switcher is capable of equalizing and reclocking all common serial digital signals, since it supports both standard and high definition signals. This makes it suitable for any application. The switcher’s versatility is illustrated by its ability to switch from SD to HD, SD to 3G, HD to 3G, and vice-versa. Another feature of this switcher is its ability to vertical interval switch when the inputs are synchronous. Vertical interval switching means that the switching takes place in the vertical interval of the video and therefore no glitch is seen in the active area of the video.

The 4x1 3G/HD/SD-SDI Switcher is a 1 RU chassis that is housed in the same case as the well-accepted 700 series. A black front panel distinguishes between the two series. Three 500 or 700 series can be mounted in the PRT-700 rack tray (sold separately).
