Notes:
  1. All specifications in this table are based on estimates and simulations or empirical data. These specifications will be updated with characterized data from silicon measurements at a later date.
  2. The current supplied to the DIMM modules is not included in this specification.
  3. Includes DC errormeasured on package pins.
  4. No requirement on the breakdown of DC noise.
  5. The voltage specification requirements are measured on package pins as near as possible to the processor with an oscilloscope set to 100 MHz bandwidth, 1.5 pF maximum probe capacitance, and 1 MΩ minimum impedance. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from the system is not coupled into the oscilloscope probe.
