Packaging/Interconnects: Matched-Impedance Connector Module Targets 0.5 To 3.2 Gbits/s

The FCN-261Z00x matched-impedance loop-back connector module is designed for testing systems operating at 500 Mbits/s to 3.2 Gbits/s per channel. Representing an expansion of the high-speed microGiGaCNTM differential connector series, it uses an internal matched-impedance pc board to perform signal testing. Crosstalk is under 4%, and in-pair skew is under 5 ps. It fits the current form factor of the InfiniBand/IEEE 802.3ak CX4 4x and 12x backshells and measures 48.9 by 71.9 mm (which includes the latching mechanism). Thumbscrew versions will be available in the third quarter for Serial Attached SCSI and Serial ATA-2 configurations. Available from stock, a 12x loopback unit costs $38.75 and a 4x unit costs $31.26, both in lots of 50 to 100.
