Hardware and software power-down mode
The ADF4106 frequency synthesizer can be used to implement
local oscillators in the up-conversion and down-conversion
sections of wireless receivers and transmitters. It consists of a
low noise, digital phase frequency detector (PFD), a precision
charge pump, a programmable reference divider, programmable
A counter and B counter, and a dual-modulus prescaler (P/P + 1).
The A (6-bit) counter and B (13-bit) counter, in conjunction
with the dual-modulus prescaler (P/P + 1), implement an N
divider (N = BP + A). In addition, the 14-bit reference counter
(R Counter) allows selectable REFIN frequencies at the PFD
input. A complete phase-locked loop (PLL) can be implemented
APPLICATIONS
if the synthesizer is used with an external loop filter and voltage
controlled oscillator (VCO). Its very high bandwidth means

that frequency doublers can be eliminated in many high
frequency systems, simplifying system architecture and
reducing cost.
