ADF4193WCCPZ-RL7

Overview

The ADF4193WCCPZ-RL7 is a fast-settling fractional-N PLL frequency synthesizer designed for wireless base station applications. It features a digital phase frequency detector, precision differential charge pump, and on-chip low-noise differential amplifier. The device supports RF input frequencies up to 3.5 GHz with a maximum prescaler output of 470 MHz. Operating voltages include AVDD/DVDD/SDVDD from 2.7 V to 3.3 V and VP supplies from 4.5 V to 5.65 V. Total supply current (IDD) reaches a maximum of 35 mA across all domains. It operates within an extended temperature range of -40°C to +105°C.

Feature Summary

• Fast settling architecture enabling GSM band frequency hop in 5 µs with phase settled by 20 µs
• Normalized phase noise figure of merit of -216 dBc/Hz
• Digitally programmable output phase with 0.5° rms phase error at 2 GHz RF output
• On-chip differential amplifier converts charge pump output to single-ended voltage for external VCO

Applications

• GSM/EDGE base stations
• PHS base stations
• Instrumentation and test equipment

Procurement Notes

Verify the W suffix indicates automotive qualification (-40°C to +105°C). Confirm LFCSP-32 package compatibility with PCB design guidelines. Ensure VP pins are supplied within 4.5 V to 5.65 V limits. Check humidity sensitivity handling requirements during assembly.

Selection Notes

Select this component when ping-pong synthesizers must be replaced by a single unit. Suitable for designs requiring sub-20 µs phase settling times. Verify loop filter design using ADIsimPLL tool. Ensure reference input frequency matches PFD capabilities up to 30 MHz.

Part Context

Part of the Analog Devices ADF4193 family. The WCCPZ variant denotes automotive grade qualification and LFCSP-32 packaging. Replaces older dual-PLL architectures to reduce cost, complexity, and PCB area.
