GENERAL DESCRIPTION
The ADF4110 family of frequency synthesizers can be used to
implement local oscillators in the upconversion and downcon-
version 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 phase-locked loop (PLL) can be implemented
if the synthesizer is used with an external loop filter and voltage
controlled oscillator (VCO).
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.
