STCD1020_10 Datasheet, PDF (14/40 Pages) STMicroelectronics – Multichannel clock distribution circuit

Application information
STCD1020, STCD1030, STCD1040
of the 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).
