OUTPUT BUFFER CHARACTERISTICS
The following table describes output-buffer Voltage vs. Current (V/I) characteristics that are sufficient to meet the requirements of registered
DDR DIMM performance and timings. These characteristics are not necessarily production tested but can be guaranteed by design or
characterization. Compliance with these curves is not mandatory if it can be adequately demonstrated that alternate characteristics meet the
requirements of the registered DDR DIMM application.
