7743DLY-HD is an Evertz video signal processing module delivering programmable delay for HD-SDI paths in modular broadcast frames. It supports HD-SDI and 3G-SDI formats, including SMPTE 259M, 292M, and 424M, with clock/data recovery, reclocking, and signal equalization to preserve integrity over typical cable lengths. It provides a configurable delay range, status indicators, and hot-swap compatibility for rack integration in standard Evertz frames.
