The Extron FOX I/O 88 HD-SDI board is available as an option for the FOX Matrix 3200 and FOX Matrix 7200 Modular Fiber Optic Matrix Switchers, and enables connection to local 3G-SDI-equipped devices. This board offers an 8x8 configuration for switching and distribution of signals up to 2.97 Gbps, including 3G-SDI, HD-SDI, and SDI. With this board, the FOX Matrix 3200 and FOX Matrix 7200 can be configured as dedicated 3G-SDI matrix switchers, or with a combination of 3G-SDI and fiber optic matrix switching. The FOX I/O 88 HD-SDI board is compliant with SMPTE 259M, 292M, 424M, and ITU digital video standards.

The FOX I/O 88 HD-SDI board is hot-swappable, and each input and output is individually buffered to maximize performance with virtually no crosstalk. To optimize SDI signal transmission to and from the board, input signals are automatically equalized, and output signals are reclocked. The FOX Matrix 3200 and FOX Matrix 7200 provide separate bi-level and tri-level references for correct vertical interval switch timing.

The FOX I/O 88 HD-SDI board enables a local BNC connection to the FOX 3G HD-SDI fiber optic extender for 3G-SDI. Incoming signals from the FOX 3G HD-SDI can then be routed to the board's BNC outputs, or through the fiber optic outputs to remote FOX 3G HD-SDI units. Similarly, local BNC inputs can be output on fiber or BNC. In broadcast and production applications, a 3G-SDI-equipped FOX Matrix 3200 or FOX Matrix 7200, together with several FOX 3G HD-SDI units, offers expanded opportunities for system integration. For example, they can be used to route signals to and from local editing equipment, while also providing the capability to receive or transmit 3G-SDI signals very long distances to devices in remote locations, such as cameras and production monitors.
