GENERAL DESCRIPTION
The ADF4110 family of frequency synthesizers can be used
to implement local oscillators in the upconversion and down-
conversion sections of wireless receivers and transmitters. They
consist 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 (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 imple-
mented 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.
