OSCIN supports single or differential-ended clock. There must be a AC-coupling capacitor in series before the device pin. The OSCIN inputs are high-impedance CMOS with internal bias voltage. TI recommends putting termination shunt resistors to terminate the differential traces (if there are 50-Ω characteristic traces, place 50-Ω resistors). The OSCIN_P and OSCIN_N side must be matched in layout. A series AC-coupling capacitors must immediately follow OSCIN pins in the board layout, then the shunt termination resistors to ground must be placed after.
Input clock definitions are shown in Figure 8-1.
