(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, howev er it is understood that the relationship between the average timing and the absolute instantaneous timing holds all the times (min. and max of spec values are to be used for calculations). 12) 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 . parameter symbol ddr2?667 unit note 1)2)3)4)5)6)7) 8) min. max.

t qhs , where: t hp is the minimum of the absolute half period of the actual input clock; and t qhs is the specification value under the max column. {the less half-pulse width distortion present, the larger the t qh value is; and the larger the valid data eye will be.} examples: 1) if the system provides t hp of 1315 ps into a ddr2?667 sdram, the dram provides t qh of 975 ps minimum. 2) if the system provides t hp of 1420 ps into a ddr2?667 sdram, the dram provides t qh of 1080 ps minimum. 27) t qhs accounts for: 1) the pulse duration distortion of on-ch ip clock circuits, which repr esents how well the actual t hp at the input is transferred to the output; and 2) the worst case push-out of dq s on one transition followed by the worst case pull-in of dq on the next transition, both of which are independent of each other, due to data pin skew, output pattern effects, and pchannel to n-channe l variation of the output drivers. 28) t rpst end point and t rpre begin point are not referenced to a specific voltage level but specify when the device output is no longer driving ( t rpst ), or begins driving ( t rpre ). figure 2 shows a method to calculate these points when the device is no longer driving ( t rpst ), or begins driving ( t rpre ) by measuring the signal at two different voltages. the actual voltage measurement poi nts are not critical as long as the calculation is consistent. 29) when the device is operated with i nput clock jitter, this parameter needs to be derated by the actual t jit.per of the input clock. (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!). 30) 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!). 31) for these parameters, the ddr2 sdram device is characterized and verified to support t nparam = ru{ t param / t ck.avg }, which is in clock cycles, assuming all input cl ock jitter specifications are satisfied. for example, the device will support t nrp = ru{ t rp / t ck.avg }, which is in clock cycles, if all input clock jitter specifications are me t. this means: for ddr2?667 5?5?5, of which t rp = 15 ns, the device will support t nrp = ru{ t rp / t ck.avg } = 5, i.e. as long as the input cloc k jitter specifications are met, prechar ge command at tm and active command at tm + 5 is valid even if (tm + 5 - tm) is less than 15 ns due to input clock jitter. 32) t wtr is at lease two clocks (2 x t ck ) independent of operation frequency.

(mr, a12 = ?0?) a fast power-down exit timing t xard can be used. in ?low active power-down mode? (mr, a12 =?1?) a slow power-down exit timing t xards has to be satisfied. 22) wr must be programmed to fulfill the minimum requirement for the t wr timing parameter, where wr min [cycles] = t wr (ns)/ t ck (ns) rounded up to the next integer value. t dal = wr + ( t rp / t ck ). for each of the terms, if not already an integer, round to the next highest integer. t ck refers to the application clock period. wr refers to the wr parameter stored in the mrs. symbol parameter / condition values unit note min. max. t aond odt turn-on delay 2 2 nck 1) 1) new units, ' t ck.avg ' and 'nck', are introduced in ddr2-667 and ddr2-800. unit ' t ck.avg ' represents the actual t ck.avg of the input clock under operation. unit 'nck' represents one clock cycle of the input clock, counting the actual clock edges. note that in ddr2-4 00 and ddr2-533, ' t ck ' is used for both concepts. example: t xp = 2 [nck] means; if power down exit is registered at tm, an active command may be registered at tm + 2, even if (tm + 2 - tm) is 2 t ck.avg + t epr.2per(min) . t aon odt turn-on t ac.min t ac.max + 0.7 ns ns 1)2) 2) odt turn on time min is when the device leaves high impedance and odt re sistance begins to turn on. odt turn on time max is w hen the odt resistance is fully on. both are measured from t aond , which is interpreted differently per speed bin. for ddr2-667/800, t aond is 2 clock cycles after the clock edge that registered a firs t odt high counting the actual input clock edges. t aonpd odt turn-on (power-down modes) t ac.min + 2 ns 2 t ck + t ac.max + 1 ns ns 1) t aofd odt turn-off delay 2.5 2.5 nck 1) t aof odt turn-off t ac.min t ac.max + 0.6 ns ns 1)3) 3) odt turn off time min. is when the device starts to turn off odt resistance. odt turn off time max is when the bus is in high impedance. both are measured from t aofd . both are measured from t aofd , which is interpreted differently per speed bin. for ddr2-667/800,if t ck.avg = 3 ns is assumed, t aofd = 1.5 ns (0.5 3 ns) after the second trailing clock edge counting from the clock edge that registered a first odt low and by counting the actual input clock edge. t aofpd odt turn-off (power-down modes) t ac.min + 2 ns 2.5 t ck + t ac.max + 1 ns ns 1) t anpd odt to power down mode entry latency 3 ? nck 1) t axpd odt power down exit latency 8 ? nck 1)
