DB13W3 (13W3) is a style of D-subminiature connector used for analog video interfaces. The 13 refers to the total number of pins, the W refers to workstation and the 3 refers to the number of high-frequency pins. The connector was something of a pseudo-standard for high-end graphical workstations from the early 1990s to the early 2000s.
