High speed data links for signal integrity

18 May 2005 Interconnection

Samtec's Flex Data Links are available with socket and terminal strip interfaces on 0,5 mm pitch (HFHM2-DP Series) and 0,8 mm pitch (HFEM-SE, HFEM-DP and HFEM2-DP Series) for high speed board-to-board connections.

Typical performance for the 0,5 mm pitch system is more than 6 Gbps/pair with 20 signal pairs per bank for a 127 mm length. For the 0,8 mm pitch system, typical performance is up to 4 Gbps per signal line for a 127 mm length and up to 2,5 Gbps per signal line for a 254 mm length.

A wide variety of options are available as standard including single-ended and differential signal routing, two layer and three layer designs, mounting and locking options for rugged applications, and socket and terminal terminations.

A new standard with Samtec is a 0,8 mm pitch Q Strip socket or terminal strip on one end and a standard 43 pin 0,5 mm pitch ZIF flex termination on the other (ZHFH Series) providing 14 signal pairs with ground pins surrounding each pair.
