DVI Connector Pin Pitch and Specifications

This article provides an overview of the pin pitch and physical contact spacing of the standard Digital Visual Interface (DVI) connector. It details the exact center-to-center measurements of the primary digital pin matrix, explores the layout differences between digital and analog variants, and highlights the engineering standards that ensure mechanical and electrical compatibility across DVI hardware.

The primary pin pitch on a standard DVI connector's digital grid is 1.905 mm (0.075 inches). This measurement represents the center-to-center distance between adjacent pins, applying uniformly to both the horizontal and vertical spacing across the connector's 24-pin digital array (configured as three rows of eight pins).

In connectors that support analog signals, such as DVI-I (integrated) and DVI-A (analog only), an additional section called the "MicroCross" area is present alongside the 24-pin grid. This section houses a flat horizontal blade contact for ground and four surrounding round pins (C1 through C4) dedicated to analog red, green, blue, and horizontal sync signals. The spacing in this analog cluster differs from the 1.905 mm grid to accommodate higher-frequency isolation and proper impedance matching.

The 1.905 mm pitch is equivalent to three-quarters of the standard 2.54 mm (0.1-inch) pitch common in electronics. This tight spacing allows the standard DVI shell to accommodate up to 29 total pins (24 digital contacts, 4 analog contacts, and 1 ground blade) within a compact footprint while preserving sufficient clearance to prevent short circuits, crosstalk, and mechanical wear during mating.
