Connectors Fit in PCIe Architectures
Acting as point-to-point full duplex I/O bus connectors, ERNI Electronics’ X1, X4, X8, and X16 right-angled card edge connectors meet the requirements of PCIe architectures. The 1 mm centerline family provides board-to-board distances from 5.84 mm to 16.68 mm, compatibility with 1.6 mm to 2.4 mm thick motherboards and 1.6 mm thick daughter cards, and stack heights of 5.84 mm, 11.17 mm, and 16.68 mm. The interconnects come in a 4-row format with 2 mm pitch, molded polarization keys, solder termination with a termination length of 2.54 mm, and provision of 2 holes for locator pegs. Each serial link supports 2.5 Gb/s per direction in 100 W Gen 1 systems in servers, workstations, desktop PCs (as a AGP replacement), and storage applications.
