Single, Integer-N 3.0 GHz PPL With Programmable Prescaler And Charge Pump

The ADF4110 family of Frequency Synthesizers CAN be used to implement local Oscillators in the up-conversion and down-conversion sections of Wireless receivers and transmitters. They consist of 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).
Control of all the on-chip Registers is via a simple 3-wire Interface The devices operate with a power supply ranging from 2.7 V to 5.5 V and CAN be powered down when not in use.
