PARAMETER(3) TEST CONDITIONS MIN TYP MAX UNIT
VOH(DC) DC output high voltage for DMD_LS_WDATA and DMD_LS_CLK 0.7 × VCC18 V
VOL(DC) DC output low voltage for DMD_LS_WDATA and DMD_LS_CLK 0.3 × VCC18 V
VOH(AC)(1) AC output high voltage for DMD_LS_WDATA and DMD_LS_CLK 0.8 × VCC18 VCC18 + 0.5 V
VOL(AC)(2) AC output low voltage for DMD_LS_WDATA and DMD_LS_CLK -0.5 0.2 × VCC18 V
Slew rate DMD_LS_WDATA and DMD_LS_CLK VOL(DC) to VOH(AC) for rising edge and VOH(DC) to VOL(AC) for rising edge 1.0 3.0 V/ns
DMD_DEN_ARSTZ VOL(AC) to VOH(AC) for rising edge 0.25
DMD_LS_RDATA 0.5
(1) VOH(AC) maximum applies to overshoot. When the DMD_LS_WDATA and DMD_LS_CLK lines include a proper 43-Ω series termination resistor, the DMD operates within the LPSDR input AC specifications.
(2) VOL(AC) minimum applies to undershoot. When the DMD_LS_WDATA and DMD_LS_CLK lines include a proper 43-Ω series termination resistor, the DMD operates within the LPSDR input AC specifications.
(3) See Figure 6-3 for DMD_LS_CLK, and DMD_LS_WDATA rise and fall times. See Figure 6-4 for DMD_DEN_ARSTZ rise and fall times.
