1.6.2.2. Determine if your system requires voltage-referenced signaling

  • Voltage-referenced signaling reduces the effects of simultaneous switching outputs (SSO) from pins changing voltage levels at the same time (for example, external memory interface data and address buses).
  • Voltage-referenced signaling provides an improved logic transition rate with a reduced voltage swing, and minimizes noise caused by reflection with a termination requirement.
  • Additional termination components are required for the reference voltage source (VTT).
