Fujitsu Components America, Inc. released the first in a series of new connector modules for 4x I/O to support high-speed signal transmission. The new modules offer a compact, cost-efficient way to increase I/O port density and available printed circuit board space, while simplifying high-speed signal routing on the main PCB.
The first module in Fujitsu's Multi-IO microGiGaCN series is the FCN-268Y032-A. This is a 2x2-stacked module of four, 4x links that meets InfiniBand, InfiniBand DDR, 10G Fiber Channel, and 10GBase-CX4 data rates in a 4-channel, bi-directional data-transfer mode. The module is designed to accommodate up to five modules (20 links) installed in a 1U configuration on a motherboard.
Each 2x2 module mounts to the PCB via a single, Fujitsu high-speed, board-to-board mezzanine connector, which is rated to 10Gbps. Using only a single interface connector per module simplifies board design and reduces component count on the pcb. In addition, the module’s die-cast housing offers a robust, mechanical interface and improved EMI protection. Options for link-status LEDs and media detect circuitry are planned on future versions.
The FCN-268Y032-A has a 30VAC rating and 240m-ohm contact resistance (signal), 180m ohms (ground). When mated, it has a differential characteristic impedance of 100 ohms +/-10 percent with 100ps rise time.
The FCN-268Y032-A is priced at $37.50 in 1K quantities. The high-speed interface connector is priced at $7.39 in 1K quantities.
