Dual Rf Pll Frequency Synthesizers - Analog Devices

The ADF4206 family of dual Frequency Synthesizers ADF4206 ADF4207 ADF4208 CAN be used to implement local Oscillators in the upconversion and downconversion sections of Wireless receivers and transmitters. Each synthesizer 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 (11-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 frequen- cies at the PFD input. The on-chip Oscillator circuitry allows the reference input to be derived from crystal Oscillators A complete PLL (Phase-Locked Loop) CAN be implemented if the synthesizers are used with an external loop lter and VCOs (Voltage Controlled Oscillators). 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.
