10.5.2 OSCout0_TYPE

The OSCout0 clock output has a programmable output type. The OSCout0_TYPE register sets the output type to LVDS, LVPECL, LVCMOS, or powers down the output buffer. Note that LVPECL supports four different amplitude levels and LVCMOS supports dual and single LVCMOS outputs with inverted, and normal polarity of each output pin for maximum flexibility.

To turn on the output, the OSCout0_TYPE must be set to a non-power down setting and enabled with EN_OSCoutX, OSCout Output Enable.

12 (0x0C) (1)LVCMOS (Norm/Low)
13 (0x0D) (1)LVCMOS (Inv/Low)
14 (0x0E) (1)LVCMOS (Low/Low)
(1) TI recommends to use one of the complementary LVCMOS modes. Best noise performance is achieved using LVCMOS (Norm/Inv) or LVCMOS (Inv/Norm) due to the differential switching of the outputs. The next best performance is achieved using an LVCMOS mode with only one output on. Finally, LVCMOS (Norm/Norm) or LVCMOS (Inv/Inv) have the create the most switching noise.
