For high-speed applications, the TwinMezz high-density mezzanine connector system streams data at a rate of 20+ Gb/s. Reportedly, the connector system exhibits well-matched impedance, low insertion loss, and low crosstalk. Configurations with six differential signal pairs per column provide maximum signal density, delivering 25 high-speed signal pairs in a square centimeter or 161 signal pairs in a square inch. The system’s hermaphroditic design mates to itself and supports stack heights ranging from 12 mm to 40 mm with 200 to 800 total contacts. Options include integrated molded or optional metal guides and the capability to mix signal and power wafers in a single connector. FCI USA INC., Etters, PA. (800) 237-2374.
