Logic 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.
XTAL_CLK_IN
Input
Reference Crystal Pin/27MHz clock input. Connect to an external
circuit as shown in Figure 6-1: GS6152 Typical Application Circuit or
to a digital clock source (XTAL_BUF_OUT of another GS6152 or
GS6151). Connect to ground if operating referenceless.
XTAL_CLK_OUT
Output
Reference Crystal Pin. Connect to a external circuit as shown in Figure
6-1: GS6152 Typical Application Circuit, or leave unconnected if
XTAL_CLK_IN is driven by an external clock source or if XTAL_CLK_IN
is connected to ground (referenceless).
