Description
PLL Reference Input.
Complementary PLL Reference Input.
Power Supply (3.3 V).
Charge Pump Power Supply. It should be greater than or equal to VS.
VCP can be set as high as 5.5 V for VCOs, requiring extended tuning range.
Charge Pump Output.
Clock Input. Used to connect external VCO/VCXO to feedback divider, N. CLK2 also drives the
distribution section of the chip and may be used as a generic clock input when PLL is not used.
Complementary Clock Input. Used in conjunction with CLK2.
Clock Input. Drives distribution section of the chip.
Complementary Clock Input. Used in conjunction with CLK1.
Multipurpose Input. May be programmed as a reset (RESETB), sync (SYNCB), or power-down (PDB) pin.
This pin is internally pulled down by a 30 kΩ resistor. If this pin is left NC, the part is in reset by default.
To avoid this, connect this pin to V
