C for the DSCN. All currents into device pins shown as positive, out of device pins as negative, all voltages referenced to ground unless otherwise noted. Rise and fall time are given for MOS logic levels; i. The high current transient as high as 1. If the external interconnecting lead from the driving circuit to V – is electrically long, or has significant.

The clock signals for the MM have three requirements. These requirements, high speed, large voltage swing and. All of these problems have the po. Line ringing comes from the fact that at a high enough.

Suffice it to say here, that reliable memory boards can be. Figure 3 shows the clock specification. The internal circuitry needs this. Controlling the clock ringing is particularly difficult because of. In this case it is 1V out of 20V or.

Ringing can be controlled by damping the clock. Damping the clock driver by placing a resistance in series. Clock Waveforms Voltage and Current. Because of the amount of current that the clock driver must. This is very impor.

Figure 4 gives the idealized. The size of datasheey damping resistor. As can ds0026 seen the current is significant. It must be determined empirically. Any significant inductance in. Limiting dataeheet inductance of the clock lines can be accom. A bypass capacitor, as close as possible to the. When minimizing the length of clock lines it is impor.

The size of the bypass capacitor depends on. Using a low induc. Because of this, memory. Another helpful technique is to run the V DD and. V SS lines, to the clock driver, adjacent to each other. Using multilayer printed circuit boards with clock lines sand. While discussing the clock driver, it should be pointed out. It also serves the function. It is possible to couple current noise into the input without. Unfortunately multilayer printed circuit boards.


Since the noise is difficult to. This has been a hypothetical example to emphasize that. Lastly, the clock lines must be considered as noise genera. In this example, 1 pF of parasitic capaci.

Figure 5 shows a clock coupled through a parasitic. A parasitic lumped line inductance, L, is also. Of course ds00266 is stretching. Let us assume, for the sake of argument, that C C is. However, it does point out.

The output is current, so it is more meaningful to examine. The current would be: This exceeds the total output current swing so it is obviously. Clock coupling to inputs and outputs can be minimized by. All of these tech. Ds0026 considering clock coupling it is also important to have a. With a clock transition of 20V the magnitude of the voltage.

As an example, for the MM, cou.

On the other hand the address. A critical component is any component of a life. Life support devices or systems are devices or.
