GNDcp_aux (Note 1)
Power and ground
Auxiliary charge pump ground.
22
Fvco_aux
Input
Auxiliary VCO complimentary differential input.
23
Fvco_aux
Input
Auxiliary VCO differential input.
24
VCCcml_aux
(Note 1)
Power and ground
ECL/CML 3 V. Removing power safely powers down the associated divider chain and charge pump.
25
GNDdigital (Note 1)
Power and ground
Digital ground.
26
VCCdigital (Note 1)
Power and ground
Digital 3 V.
27
Data
Digital input
Serial address and data input pin. Address bits are followed by data bits.
28
CS
Digital input
Active low enable pin. Enables loading of address and data on the Data pin on the rising edge of Clock.
When CS goes high, data is transferred to the register indicated by the address. Subsequent clock edges
are ignored.
Note 1: Associated pairs of power and ground pins must be decoupled using 0.1
F capacitors.
