Hi,=20 Placing one termination at the end of the clock will be better. Regards Alexandre AMEDEO -----Message d'origine----- De : si-list-bounce@xxxxxxxxxxxxx [mailto:si-list-bounce@xxxxxxxxxxxxx]De la part de J.Jebakumar Samuel Envoy=E9 : mercredi 29 ao=FBt 2007 13:54 =C0 : si-list@xxxxxxxxxxxxx Objet : [SI-LIST] DDR3 On-Board Hi Guys, While using DDR3 on board, the same clock travels to four chips and is routed serially (fly-by topology). I am planning to place one = termination near each chip. Will this be better or placing a termination resistor = at the end of the clock would be better?
