GENERAL DESCRIPTION
The ADF4210/ADF4211/ADF4212/ADF4213 is a dual frequency
synthesizer that can be used to implement local oscillators (LO)
in the upconversion and downconversion sections of wireless
receivers and transmitters. They can provide the LO for both
the RF and IF sections. They consist of a low-noise digital PFD
(Phase Frequency Detector), a precision charge pump, a pro-
grammable reference divider, programmable A and B Counters
and a dual-modulus prescaler (P/P + 1). The A (6-bit) and B
(12-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 lter and VCO (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 V and can be powered down when not in use.
