JAZiO ™ IncorporatedPlatform2000 2 Alternating References Larger differential signal when signal changes Reduces signal slew rate to achieve the same differential swing Instead of static VREF, JAZiO uses dynamic Voltage/Timing Reference (VTR) VTR Data Input VREF Pseudo Differential JAZiO Data Input

3. JAZiO ™ IncorporatedPlatform2000 3 Voltage to Time Domain Transposition Change No Change pp D D Vref Vol Voh Full Differential JAZiO Pseudo Differential JAZiO transposes the voltage domain to the time domain, since signal binary is defined in the time domain. JAZiO binary margin is more dependent on transition time rather than voltage swing. Change vs No Change GapPeak to Peak DifferenceAbove or Below Reference

4. JAZiO ™ IncorporatedPlatform2000 4 Change /No Change Concept Comp A Data In VTR Data In Comp A No Change This band is based on process mismatch (device W, L, etc.), reflection or overshoot (discontinuity, termination, inductance, etc.). 3 Case 3: Comp A remains High (weakly) while the Data Output retains the previous data Case 1: Comp A amplifies the change and the data passes through the Steering Logic Change 1 The time gap is used by the steering logic to pass the change or block the no-change from reaching the data output 1

20. JAZiO ™ IncorporatedPlatform2000 20 Internal Application Example (SOC, Embedded, Etc.) JAZiO is well suited for large internal bus structures (SOC), which have greater than 2 pf/line loading. JAZiO uses ~0.3V swing with small transmitters and receivers to easily substitute traditional full swing buses. JAZiO also scales as the technology changes (process, voltage, etc.). JAZiO makes implementation easier and takes the burden off of meeting set-up time, hold time, and rise/fall times. JAZiO requires no PLL or DLL or repeater circuitry. JAZiO can support multiple frequencies on a given bus structure, it can be used synchronously or asynchronously, can support multiple supply voltages on the same bus, thus allowing the user flexibility in optimizing any implementation.
