... Device operation 2 Device operation The STCD1020, STCD1030 and STCD1040 are buffered unity gain clock distribution circuits. They accept the clock input from an external clock source and send buffered outputs to different devices. Each clock output of the STCD1020, STCD1030 and STCD1040 can be enabled for the device connected to it ...

... 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 ...

... STCD1020, STCD1030 and STCD1040. The proper DC voltage is around half of the supply. The connection of the DC-CUT capacitor and bias for the STCD1020, STCD1030 and STCD1040 is only needed when the output of VCTCXO voltage level exceeds the supply of the clock distribution circuit (see Figure 10. Connection of the DC-CUT capacitor and bias ...
