Connector module eases signal routing

Fujitsu Components America Inc. has launched the first in a series of connector modules for 4x I/O to support high-speed signal transmission. The modules increase I/O port density and available PCB space while simplifying high-speed signal routing on the main board, Fujitsu said.

The first module in the Multi-IO microGiGaCN series is the FCN-268Y032-A, a 2-by-2-stacked module of four, 4x links that meets Infiniband, Infiniband DDR, 10Gbit Fiber Channel and 10GBase-CX4 data rates in a four-channel, bidirectional data transfer mode. The module is designed to accommodate up to five modules (20 links) installed in a 1U configuration on a motherboard.

The module has a 30Vac rating and 240 milliohms contact resistance (signal)/180 milliohms (ground). When mated, it has a differential characteristic impedance of 100 ohms ±10 percent with a 100ps rise time.

Each 2-by-2 module mounts to the PCB via a Fujitsu-developed high-speed, board-to-board mezzanine connector rated to 10Gbps. Using one interface connector per module simplifies board design and reduces the component count on the board, said the company.

The module's die-cast housing is intended to provide a robust mechanical interface and improved EMI protection, according to the company. Options for link-status LEDs and media-detection circuitry are planned for future versions.

The FCN-268Y032-A is priced at $37.50 in quantities of 1,000. The interface connector is priced at $7.39 in quantities of 1,000.
