ADF4193BCPZ-RL7

Overview

The ADF4193BCPZ-RL7 is a low phase noise, fast settling fractional-N PLL frequency synthesizer manufactured by Analog Devices Inc. It features a digital phase frequency detector, precision differential charge pump, and on-chip differential amplifier. The device supports RF input frequencies up to 3.5 GHz and operates with supply voltages of 2.7 V to 3.3 V for logic/analog sections and 4.5 V to 5.65 V for high-voltage pins. Packaged in a 32-lead LFCSP, it is designed for rapid frequency hopping within GSM time slot guard periods.

Feature Summary

• Fast settling architecture enabling frequency hops across the GSM band in 5 µs with phase settled by 20 µs
• Low phase noise figure of merit of −216 dBc/Hz and 0.5° rms phase error at 2 GHz RF output
• Integrated Σ-Δ based fractional interpolator and programmable modulus fractional-N division
• On-chip low noise differential amplifier converting differential charge pump output to single-ended VCO voltage

Applications

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

Procurement Notes

Verify the B version suffix indicates an operating temperature range of -40°C to +85°C. Confirm the RL7 suffix corresponds to the reel packaging format containing 1500 units. Ensure compatibility with the specified 32-lead LFCSP footprint during procurement planning.

Selection Notes

Select this component when replacing ping-pong synthesizers to reduce PCB area and complexity. Designers must account for separate power supplies: AVDD/DVDD (2.7–3.3 V) and VP1/VP2/VP3 (4.5–5.65 V). Use ADIsimPLL software for loop filter design to meet specific phase noise and spur requirements.

Part Context

This part belongs to the ADF4193 series of frequency synthesizers. The BC designation identifies the specific grade and package variant within the family. It serves as a direct replacement for older dual-PLL architectures in wireless infrastructure, offering a single-chip solution for local oscillator generation in upconversion and downconversion sections.
