Cables for high-speed test

31 March 2010 Interconnection

Samtec’s new high-speed Edge Rate Twinax, Micro Coax and Direct-to-Lead Coax cable assemblies incorporate its rugged 0,8 mm pitch Edge Rate terminals and sockets (ERM8/ERF8 series) which are designed for enhanced signal integrity and impedance control, and reduced broadside coupling. The result is a robust family of cable-to-board interconnect solutions for high-speed and long cable run applications as well as for emulation testing (the ERF8 series connector has been specified as the standard board level interface by NEXUS, POWER.org and ARM). All three systems feature rugged friction latches.

Edge Rate 34 AWG, 50 Ω coax cable assemblies include the Micro Coax Cable (ERCD series) and the Direct-to-Lead Coax Cable (ERCDA series) which is rated from 890 MHz (1 metre) to 7,90 GHz (15 mm) and is hot pluggable. The Direct-to-Lead cable is also designed to optimise signal integrity with a patent-pending direct termination that eliminates the need for a PCB. The Edge Rate 30 AWG, 100 Ω Differential Pair Twinax Cable (ERDP series) is rated from 1,41 GHz (1 metre) to 6,33 GHz (15 mm) and is also hot pluggable. The Micro Coax and Twinax assemblies also have an optional squeeze latch system that prevents unintentional de-mating.
