9 / 14 page Data Sheet E0079N20 (Ver 2.0) 9 MC-4R256FKE8D AC Electrical Specifications Symbol Parameter and Conditions MIN. TYP. MAX. Unit Z Module Impedance of RSL signals 25.2 28.0 30.8 Ω Module Impedance of SCK and CMD signals 23.8 28.0 32.2 TPD Average clock delay from finger to finger of all RSL clock nets 1.56 ns (CTM, CTMN,CFM, and CFMN) ∆TPD Propagation delay variation of RSL signals with respect to TPD Note1,2 −21 +21 ps ∆TPD-CMOS Propagation delay variation of SCK signal with respect to an average clock delay Note1 −250 +250 ps ∆TPD- SCK,CMD Propagation delay variation of CMD signal with respect to SCK signal −200 +200 ps Vα/VIN Attenuation Limit -845 16.0 % -745 16.0 -653 12.5 VXF/VIN Forward crosstalk coefficient -845 4.0 % (300ps input rise time 20% - 80%) -745 4.0 -653 4.0 VXB/VIN Backward crosstalk coefficient -845 2.0 % (300ps input rise time 20% - 80%) -745 2.0 -653 2.0 RDC DC Resistance Limit -845 0.8 Ω -745 0.8 -653 0.8 Notes 1. TPD or Average clock delay is defined as the average delay from finger to finger of all RSL clock nets (CTM, CTMN, CFM, and CFMN). 2. If the RIMM module meets the following specification, then it is compliant to the specification. If the RIMM module does not meet these specifications, then the specification can be adjusted by the “Adjusted ∆TPD Specification” table. Adjusted ∆∆∆∆TPD Specification Symbol Parameter and conditions Adjusted MIN./MAX. Absolute Unit MIN. MAX. ∆TPD Propagation delay variation of RSL signals with respect to TPD +/ − [17+(18*N*∆Z0)] Note −30 +30 ps Note N = Number of RDRAM devices installed on the RIMM module. ∆Z0 = delta Z0% = (MAX. Z0 − MIN. Z0) / (MIN. Z0) (MAX. Z0 and MIN. Z0 are obtained from the loaded (high impedance) impedance coupons of all RSL layers on the module.) |
