(output deratings are relative to the sdram input clock.) for ex ample, if the measured jitter into a ddr2?667 sdram has t err(6-10per).min = ? 272 ps and t err(6- 10per).max = + 293 ps, then t dqsck.min(derated) = t dqsck.min ? t err(6-10per).max = ? 400 ps ? 293 ps = ? 693 ps and t dqsck.max(derated) = t dqsck.max ? t err(6-10per).min = 400 ps + 272 ps = + 672 ps. similarly, t lz.dq for ddr2?667 derates to t lz.dq.min(derated) = - 900 ps ? 293 ps = ? 1193 ps and t lz.dq.max(derated) = 450 ps + 272 ps = + 722 ps. (caution on the min/max usage!) 10) input clock jitter spec parameter. these parameters are referr ed to as 'input clock jitter s pec parameters' and these parame ters apply to ddr2?667 and ddr2?800 only. the jitter specified is a random jitter meeting a gaussian distribution. 11) these parameters are specified per their average values, howe ver it is understood that the relationship between the average timing and the absolute instantaneous ti ming holds all the times. 12) input waveform timing t ds with differential data strobe enabled mr[bit10] = 0, is referenced from the input signal crossing at the v ih.ac level to the differential data strobe crosspoint for a ri sing signal, and from the input signal crossing at the v il.ac level to the differential data strobe crosspoint for a falling signal applied to the devic e under test. dqs, dqs signals must be monotonic between v il(dc)max and v ih(dc)min . see figure 3 . 13) if t ds or t dh is violated, data corruption may occur and the data must be re -written with valid data before a valid read can be executed. 14) these parameters are measured from a data signal ((l/u)dm, (l/u)dq0, (l/u)dq1, etc.) transition edge to its respective data strobe signal ((l/u/r)dqs / dqs ) crossing. 15) input waveform timing t dh with differential data strobe enabled mr[bit10] = 0, is refe renced from the differential data strobe crosspoint to the input signal crossing at the v ih.dc level for a falling signal and from the differential data strobe crosspoint to the input signal crossing at the v il.dc level for a rising signal applied to the device under test. dqs, dqs signals must be monotonic between v il.dc.max and v ih.dc.min . see figure 3 . parameter symbol ddr2?667 unit note 1)2)3)4)5)6)7) 8) min. max.

(output deratings are relative to the sdram input clock.) for example, if the measured jitter into a ddr2?667 sdram has t jit.per.min = ? 72 ps and t jit.per.max = + 93 ps, then t rpre.min(derated) = t rpre.min + t jit.per.min = 0.9 x t ck.avg ? 72 ps = + 2178 ps and t rpre.max(derated) = t rpre.max + t jit.per.max = 1.1 x t ck.avg + 93 ps = + 2843 ps. (caution on the min/max usage!). 27) when the device is operated with i nput clock jitter, this parameter needs to be derated by the actual t jit.duty of the input clock. (output deratings are relative to the sdram input clock.) for ex ample, if the measured jitter into a ddr2?667 sdram has t jit.duty.min = ? 72 ps and t jit.duty.max = + 93 ps, then t rpst.min(derated) = t rpst.min + t jit.duty.min = 0.4 x t ck.avg ? 72 ps = + 928 ps and t rpst.max(derated) = t rpst.max + t jit.duty.max = 0.6 x t ck.avg + 93 ps = + 1592 ps. (caution on the min/max usage!). 28) dal = wr + ru{ t rp (ns) / t ck (ns)}, where ru stands for round up. wr refers to the twr parameter stored in the mrs. for t rp , if the result of the division is not already an integer, round up to the next highest integer. t ck refers to the application clock period. example: for ddr2?533 at t ck = 3.75 ns with t wr programmed to 4 clocks. t dal = 4 + (15 ns / 3.75 ns) clocks = 4 + (4) clocks = 8 clocks. 29) t dal.nck = wr [nck] + t nrp.nck = wr + ru{ t rp [ps] / t ck.avg [ps] }, where wr is the value programmed in the emr. 30) t wtr is at lease two clocks (2 x t ck ) independent of operation frequency. 31) t cke.min of 3 clocks means cke must be registered on three consecutive positive clock edges. cke must remain at the valid input level t he entire time it takes to achieve the 3 clo cks of registration. thus, after any cke tr ansition, cke may not transition from its v alid level during the time period of t is + 2 x t ck + t ih .
