DIFFERENTIAL CLOCK INPUT INTERFACE
The CLK /nCLK accepts LVDS, LVPECL, LVHSTL, SSTL, HCSL
and other differential signals. Both V
SWING and VOH must meet the
V
PP and VCMR input requirements. Figures 3A to 3E show
interface examples for the CLK/nCLK input driven by the most
common driver types. The input interfaces suggested here
FIGURE 3A. CLK/NCLK INPUT DRIVEN BY
LVHSTL DRIVER
are examples only. Please consult with the vendor of the driver
component to confirm the driver termination requirements. For
example in
Figure 3A, the input termination applies for LVHSTL
drivers. If you are using an LVHSTL driver from another
vendor, use their termination recommendation.
