A very popular connector for this purpose is AMP Mictor www.amp.com <http://www.amp.com/> , follow with High Speed Connectors - Matched Impedance. If you need higher density, you can use Teradyne Nexlev http://www.teradyne.com/prods/tcs/products/connectors/mezzanine/nexlev/i ndex.html Best regards, ----------------------------------------------------------------- Michael Khusid Ansoft Corporation SI/HF Application Engineer 25 Burlington Mall Road, 6th floor Burlington, MA 01803-4100 Tel 781-229-8900 Ext. 34 Fax 781-229-8624 --------------------- http://www.ansoft.com --------------------- -----Original Message----- From: si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx] On Behalf Of Bob Patel Sent: Monday, March 03, 2003 1:55 PM To: si_list Subject: [SI-LIST] 2.5GB/s data rate connector Hi! I needed a connector for motherboard-daughter card connection which could carry data signals running at 2.5Gb/s. Has anybody used a connector for this data rate in this application. I have used one for back plane but not for daughter-mother board. Also I need to meet the SONET jitter spec, so if anybody has been successful in using one and any tips on impelemnting it, then I would appreciate any comments. Offline reply better if vendors want to reply. THanks in advance. Bob __________________________________________________ Do you Yahoo!? Yahoo!
