PLL Frequency Synthesizer

The ADF4108 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 PFD (phase frequency detector), a precision Charge Pump a programmable reference divider, programmable A and B Counters and a dual-modulus prescaler (P/P + 1). The A (6-bit) and B (13-bit) Counters 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 PLL (phase-locked loop) CAN be implemented if the synthesizer is used with an external loop Filter and VCO (voltage controlled oscillator). Its very high bandwidth (8GHz) means that frequency doublers or prescalers CAN be eliminated in many high frequency systems, simplifying system architecture and reducing cost.
