GENERAL DESCRIPTION
The ADF4154 is a fractional-N frequency synthesizer that
implements local oscillators in the up conversion and down
conversion 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 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))). In addition,
the 4-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 a voltage-controlled oscillator (VCO).
A key feature of the ADF4154 is the fast-lock mode with a built-
in timer. The user can program a predetermined countdown
time value so that the PLL remains in wide bandwidth mode,
instead of the user having to control this time externally.
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.
