GENERAL DESCRIPTION
The ADF4216/ADF4217/ADF4218 are dual frequency synthe-
sizers that can be used to implement local oscillators (LOs) 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
(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 frequencies at the PFD input. A complete PLL (Phase-
Locked Loop) can be implemented if the synthesizers are
used with an external loop lter and VCOs (Voltage Con-
trolled 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.
