Direct Connect Horizontal (DCH) high-speed press-fit twinax cable assembly targets high-performance flyover or coplanar right angle and parallel board-to-board applications.
Features a high-retention press-fit termination offering a direct connection to the PCB. Connectorless design reportedly eliminates need for board-level connectors and transition cards. Has 2mm pitch assembly and 3mm profile ideally suited for tight quarters. Combination of varying cable lengths and multiple End 2 options provides design flexibility. 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 isolated in either four-pair or eight-pair options. Supports bandwidths beyond 28Gbps NRZ/ 56Gbps PAM4. High-speed protocol support includes IEEE CAUI-4; OIF VSR, and PCIe Gen3/Gen4.
