6.6.2 Clock Input Option 2—1.8-V LVCMOS-Compatible Clock Input
In this option, a 1.8-V LVCMOS-Compatible Clock Input is used as the external clock input to the DM6437.
The external connections are shown in Figure 6-10. The MXI/CLKIN pin is connected to the 1.8-V
LVCMOS-Compatible clock source. The MXO pin is left unconnected. The MXVSS pin is connected to
board ground (VSS). The MXVDD pin can be connected to the same 1.8-V power supply as DVDDR2
.
