Parameter Measurement Information (VDD = 2.5V ±0.2V)
Notes:
8. CL includes probe and jig capacitance.
9. IDD tested with clock and data inputs held at VDD or GND, and IO = 0mA.
10. All input pulses are supplied by generators having the following characteristics: PRR ≤10 MHz, ZO = 50 ohms.
Input slew rate = 1V/ns ±20% (unless otherwise specified).
11. The outputs are measured one at a time with one transition per measurement.
12. VTT = VREF = VDDQ/2
13. VIH = VREF + 350mV (ac voltage levels) for SSTL inputs. VIH = VDD for LVCMOS input.
14. VIL = VREF + 350mV (ac voltage levels) for SSTL inputs. VIL = GND for LVCMOS input.
15. tPLH and tPHL are the same as tpd.
