Thermal Resistance (ØCA) at Various Airflows (*estimated: final values tbd) NOTES ON SYSTEM DESIGN The R3081 has been designed to simplify the task of high- speed system design. Thus, set-up and hold-time requirements have been kept to a minimum, allowing a wide variety of system interface strategies. To minimize these AC parameters, the R3081 employs feedback from its SysClk output to the internal bus interface unit. This allows the R3081 to reference input signals to the reference clock seen by the external system. The SysClk output is designed to provide relatively large AC drive to minimize skew due to slow rise or fall times. A typical part will have less than 2ns rise or fall (10% to 90% signal times) when driving the test load. Therefore, the system designer should use care when designing for direct SysClk use. Total loading (due to devices connected on the signal net and the routing of the net itself) should be minimized to ensure the SysClk output has a smooth and rapid transition. Long rise and/or fall times may cause a degradation in the speed capability of an individual device. Similarly, the R3081 employs feedback on its ALE output to ensure adequate address hold time to ALE. The system designer should be careful when designing the ALE net to minimize total loading and to minimize skew between ALE and the A/D bus, which will ensure adequate address access latch time. IDT's field and factory applications groups can provide the system designer with assistance for these and other design issues. |
