GENERAL DESCRIPTION
The ADF4156 is a 6 GHz fractional-N frequency synthesizer
that implements local oscillators in the upconversion and
downconversion sections of wireless receivers and transmitters.
It consists of a low noise digital phase frequency detector
(PFD), a precision charge pump, and a programmable reference
divider. There is a sigma-delta (Σ-Δ) based fractional interpolator
to allow programmable fractional-N division. The INT, FRAC,
and MOD registers define an overall N divider (
N
= (
INT
+
(
FRAC/MOD
))). The RF output phase is programmable for
applications that require a particular phase relationship between
the output and the reference. The ADF4156 also features cycle
slip reduction circuitry leading to faster lock times without the
need for modifications to the loop filter.
Control of all on-chip registers is via a simple 3-wire interface.
The device operates with a power supply ranging from 2.7 V to
3.3 V and can be powered down when not in use.
