Electrical Characteristics
Absolute maximum ratings
Table 99 defines the maximum values for the voltages that the NS7520 can withstand
without being damaged.
AC characteristics
AC electrical specifications define the timing relationship between signals for
interfaces and modes within a given interface.
AC electrical specifications
The AC electrical specifications are based on the system configuration shown in
Figure 30, with a 5pF allowance for PCB capacitance and a 0.25 ns allowance for PCB
delay. The timing of the buffers, SDRAM, and the like must be added to complete
timing analysis. In systems where SDRAM is not used, two devices are expected to
replace the SDRAMs shown in Figure 30; that is, they are tied directly to the chip.
System loading information is shown in Table 100: "System loading details" on page
