Samtec recently expanded its Direct Connect™ Cable (DCC) Systems with the release of the new Direct Connect™ Horizontal (DCH) High-Speed Press-Fit Twinax Cable Assembly. This new solution targets cost-effective, high-performance flyover or co-planar, right angle and parallel board-to-board applications.
Simplifies Assembly, Ideal for High Density
Samtec DCH series features a high-retention, press-fit termination offering a direct connection to the PCB. The connectorless design eliminates the need for traditional board-level connectors and transition cards leading to simplified BOMs and reduced system costs.
The 2.00mm pitch assembly and ultra-low 3 mm profile are ideally suited for tight quarters. The combination of varying cable lengths and multiple END 2 options provide design flexibility for new and existing board designs.
Supports Next Gen Data Rates
The DCH series combines Samtec 30AWG ultra-low skew EyeSpeed® twinax cable with stitched ground pins to offer improved signal integrity and optimized differential pair signal routing.
Transmit and receive signals are easily isolated in either four-pair or eight-pair options. Bandwidths well beyond 28 Gbps NRZ/ 56 Gbps PAM4 are supported. High-speed protocol support includes:
- IEEE CAUI-4
- OIF VSR
- PCIe® Gen3/Gen4
“The new DCH series provides a unique termination for Samtec high-speed, flyover cable assemblies,” said Keith Guetig, Director of Cable Product Development at Samtec, Inc. “Our growing flyover cable assembly portfolio simplifies PCB design and limits signal degradation in high data rate applications.”
Due to its simplicity, small size and high-speed performance, DCH offers a popular “End 2” option on several HDR Cable Assemblies Available from Samtec. For example, the Flyover QSFP28 Cable Systems features DCH as one of many “End 2” options.
