This file is a PDF datasheet for Analog Devices ADF4154 fractional-N frequency synthesizer
The ADF4154 is a fractional‑N frequency synthesizer designed for up‑conversion and down‑conversion sections of wireless receivers and transmitters. It includes a low‑noise digital phase‑frequency detector, programmable charge pump, and a 3‑wire serial interface for register control. The device operates from a 2.7 V to 3.3 V supply and supports fast‑lock mode with a programmable timer.
The handbook provides a functional block diagram, timing characteristics, absolute maximum ratings, pin configuration for TSSOP and LFCSP packages, and typical performance data such as phase‑noise plots and lock‑time curves. Application areas include base stations, wireless handsets, CATV equipment, WLANs and test equipment.
| RF Input Frequency | 0.5 GHz – 4.0 GHz (‑8 dBm – 0 dBm) |
|---|---|
| Reference Input Frequency | 10 MHz – 250 MHz |
| Phase Detector Frequency (max) | 32 MHz |
| Analog Power Supply (AVop) | 2.7 V – 3.3 V |
| Low Power Sleep Mode Current | 1 pA typ |
| Operating Temperature (B version) | -40 °C – +85 °C |
The B version is rated for an industrial temperature range of –40 °C to +85 °C.
Control of all on‑chip registers is via a simple 3‑wire serial interface.
The phase detector can operate up to 32 MHz.
