Note:
Figure 8.
Connection of the source clock to MCLK
If the output of the clock source voltage level is within the supply rails of the STCD1020,
STCD1030 and STCD1040, the output of the source clock should be connected directly to
the MCLK of the clock distribution circuits. This is described in
connection of the source clock is the common case and a DC-CUT capacitor is saved on
PCB.
Figure 9.
The input clock voltage level of the STCD1020, STCD1030, and STCD1040 cannot exceed
the supply rails when it is directly connected to the source clock. If it is needed to connect a
source clock with the voltage level exceeds the supply rails of the clock distribution circuits,
the user needs to connect a DC-CUT capacitor serially as shown in
divider formed by a resistor string is also needed to set a proper DC bias for the clock input
