Preliminary data sheet
14.3.2 Equivalent input circuit
The equivalent circuit of the input clock buffer is shown in
voltage of the differential input stage is set via internal resistors of 5 kΩ resistors.
Single-ended or differential clock inputs can be selected via the SPI (see
single-ended is selected, the input pin (CLKM or CLKP) is selected via control bit
SE_SEL.
