FEATURES

T he AD F4210/AD F4211/AD F4212/AD F4213 is a

dual frequency synthesizer which can be used to

implement local oscillators in the up-conversion and

down-conversion sections of wireless receivers and

transmitters. T hey can provide the LO for both the

RF and IF sections. T hey consist of a low-noise digi-

tal 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). T he 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 15-bit reference counter (R

Counter), allows selectable REFIN frequencies at the

PFD input. A complete PLL (Phase-Locked Loop)

can be implemented if the synthesizers are used with

an external loop filter and VCO's (Voltage Controlled

Oscillators)Control of all the on-chip registers is via

a simple 3-wire interface. T he devices operate with a

3V ( ± 10%) or 5V( ± 10%) power supply and can be

powered down when not in use.
