Use ‘average’ acquisition mode of the scope 2. Measurement taken from differential wave- form 3. Slew rate measured through V_swing volt- age range centered about differential zero Slew_fall Falling slew rate 1.0 4.0 V/ns 1. Use ‘average’ acquisition mode of the scope 2. Measurement taken from differential wave- form 3. Slew rate measured through V_swing volt- age range centered about differential zero Slew_var Slew rate matching 20 % 1. Use ‘average’ acquisition mode of the scope 2. Measurement taken from single ended waveform 3. Matching applies to rising edge rate for Clock and falling edge rate for Clock#. It is measured using a +/-75mV window centered on the average cross point where Clock rising meets Clock# falling. The median cross point is used to calculate the voltage thresholds the oscilloscope is to use for the edge rate calcu- lation V_swing Differential output swing 300 mV Measurement taken from differential wave- form V_cr Crossing point voltage 250 550 mV 1. Measurement taken from single ended waveform 2. V_cross is defined as the voltage where Clock = Clock# 3. Only applies to the differential rising edge (i.e. Clock rising and Clock# falling) V_cr_dlt Variation of V_cr 140 mV 1. Measurement taken from single ended waveform 2. V_cross is defined as the voltage where Clock = Clock# 3. V_cross delta is defined as the total varia- tion of all crossing voltages of rising Clock and falling Clock# Tskew CPU[0:3] skew 50 ps Tccjitter Cycle to Cycle Jitter (CPU) 50 ps Tccjitter Cycle to Cycle Jitter (SRC) 50 ps Tccjitter Cycle to Cycle Jitter (NS_SAS) 50 ps |
