Clock Input Option 2—1.8-V LVCMOS-Compatible Clock Input
7.4.2.1
33.3-MHz System Oscillator 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 system
oscillator. The external connections are shown in
oscillator. The external connections are shown in
. The DEV_MXI/DEV_CLKIN pin is connected
to the 1.8-V LVCMOS-Compatible clock source. The DEV_MXO pin is left unconnected. The DEV_V
SS
pin
is connected to board ground (V
SS
). The DEV_DV
DD18
pin can be connected to the same 1.8-V power
supply as DV
DDR2
.
