Introduction

AI Translation

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 REF_IN 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 builtin 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.
