Notes:
1. Unless otherwise noted, 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 AC and DC error, where the AC noise is bandwidth limited to under 100 MHz, measured on package pins.
4. No requirement on the breakdown of AC versus DC noise.
5. The voltage specification requirements are measured as near as possible to the processor with an oscilloscope set to 100-
MHz bandwidth, 1.5 pF maximum probe capacitance, and 1 M 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.
6. For Voltage less than 1V, TOB will be 50 mV.
