New Development Kit from 3M Helps Design Engineers Achieve Multi-Gigahertz Performance in 2 mm Footprint
Wednesday 07. January 2009 - 3M innovators have developed a way for design engineers to achieve multi-gigahertz performance from industry standard 2 mm printed-circuit-board connectors, using 2 mm shielded controlled impedance cable assemblies.
New development kits from 3M let design engineers test drive these innovative cable assemblies for their applications.
The Shielded Controlled Impedance (SCI) Cable Assembly Development Kit, 2 mm from the 3M Electronic Solutions Division is designed to help engineers assess, test and design the appropriate high performance 2 mm SCI cable-to-board solution for their application.
When used with standard 2 mm latch/eject headers from 3M for multi-gigahertz cable-to-board applications , the SCI connectors save valuable board real estate without sacrificing performance compared to the BNC or SMA connectors frequently used with coaxial, and the specialized twinaxial connectors used with twinaxial cable. This is particularly true for applications where multiple high-speed coaxial or twinaxial cable-to-board connectors need to be bundled together.
This solution is ideal for a variety of high-performance or high-signal integrity cable-to-board applications in the industrial control/factory automation, medical, test and instrumentation, video post production equipment and military electronics industries.
Designers can use the development kit to verify signal integrity, impedance matching and crosstalk performance for designs that require up to 1 Gbps single-ended performance per signal line or 5 Gbps differential performance per signal pair, bundled multi-line cable-to-board solution requiring mechanical reliability such as that offered by a latch/eject connector.
The development kit contains everything required to assess, test and design a high performance 2 mm cable-to-board solution, including:
CD-ROM containing application note, test instruction sheet, technical sheets. The application note is illustrated with graphical data from actual lab tests under different test conditions.
Postage-paid reply card to request product updates and register the kit
2 mm SCI differential and single-ended cable assemblies (twinaxial and coaxial), 24″ length
2×25 surface mount or through-hole 2 mm latch/eject headers
2×25 carrier used for bundling together the SCI cable mount connectors
Optional specialized printed circuit board for testing
SMA connectors for testing, mounted on the PCB for development kits that include a printed circuit board
SMA connectors specified for development kits that do not include a printed circuit board
Test procedures document
Application note describing how the SCI Assembly can be used. The note is illustrated with graphical data from actual lab tests under different test conditions.
