ADF4193BCPZ

Overview

The ADF4193BCPZ is a low phase noise, fast settling fractional-N PLL frequency synthesizer manufactured by Analog Devices Inc. It operates with an RF input range of 0.4 GHz to 3.5 GHz and supports a maximum prescaler output frequency of 470 MHz. The device features a digital phase frequency detector (PFD) and a precision differential charge pump. Key electrical parameters include a normalized phase noise figure of merit of −216 dBc/Hz and a typical operating current of 22 mA at 3 V supplies. Designed for rapid frequency hopping, it achieves lock across the GSM band in 5 µs with phase settling within 20 µs.

Feature Summary

• Fast settling architecture enabling full GSM band frequency hop in 5 µs
• Normalized phase noise figure of merit of −216 dBc/Hz
• Integrated low noise differential amplifier for VCO tuning
• Digitally programmable output phase with 0.5° rms phase error at 2 GHz

Applications

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

Procurement Notes

Verify the specific suffix (e.g., BCPZ-RL7) against the manufacturer's ordering guide to confirm package type and reel quantity. Ensure the version (B or C) matches the required operating temperature range, as specifications differ between industrial and extended automotive grades. Confirm supply chain availability through authorized distributors.

Selection Notes

Select the B version for an operating temperature range of −40°C to +85°C. Select the C version for an extended range of −40°C to +105°C. Ensure external power supplies meet the specified limits: AVDD/DVDD at 2.7 V to 3.3 V, and VP pins at 4.5 V to 5.65 V. Use ADIsimPLL software for loop filter design to optimize settling time and phase noise performance.

Part Context

The ADF4193 is part of the ADF4193 series of PLL frequency synthesizers. It is designed to replace traditional ping-pong synthesizer architectures in GSM base stations, reducing PCB area and complexity. The device integrates a Σ-Δ fractional interpolator and a 4-bit reference counter to support flexible reference frequencies.
