ADF4106BRU Datasheet

Phase Locked Loops - PLL


The ADF4106BRU frequency synthesizer can be used to implementlocal oscillators in the up-conversion and down-conversionsections of wireless receivers and transmitters. It consists of a low noise, digital phase frequency detector (PFD), a precisioncharge 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 conjunctionwith the dual-modulus prescaler (P/P + 1), implement an Ndivider (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 implementedif the synthesizer is used with an external loop filter and voltagecontrolled oscillator (VCO). Its very high bandwidth means that frequency doublers can be eliminated in many high frequency systems, simplifying system architecture andreducing cost.
