SNAS811 July 2020 – May CDCE6214
The CDCE6214 provides multiple power supply pins. Each power supply supports 1.8 V, 2.5 V, or 3.3 V. Internal low-dropout regulators (LDO) source the internal blocks and allow each pin to be supplied with its individual supply voltage. The VDD_REF pin supplies the control pins and the serial interface. Therefore, any pullup resistors shall be connected to the same domain as VDD_REF. VDD_VCO powers all PLL blocks. VDDO_12 powers outputs OUT1 and OUT2. VDDO_34 powers OUT0, OUT3, and OUT4.
VDD_REF and VDDO_34 can be used for level translation operation on OUT0.
