Digital Input
Input selection control.
Used to select the high-speed input for processing through the
device. Refer to Table 4-2 for details on input selection.
Input
Reference Crystal Pin/27MHz clock input. Connect to an external
circuit as shown in Figure 6-1: GS6151 Typical Application Circuit or
to a digital clock source (XTAL_BUF_OUT of another GS6150, GS6151,
GS6152, or a 27MHz clock output from another device). Connect to
ground if operating referenceless.
