ADF4196BCPZ-RL7

Overview

The ADF4196BCPZ-RL7 is a low phase noise, fast settling, 6 GHz fractional-N PLL frequency synthesizer manufactured by Analog Devices Inc. It features a digital phase frequency detector (PFD), precision differential charge pump, and on-chip differential amplifier. The device supports RF input frequencies up to 6 GHz with an operating temperature range of -40°C to +85°C. Key electrical parameters include a normalized phase noise figure of merit of -216 dBc/Hz, a typical power supply current of 27 mA for AVDD/DVDD/SDVDD, and a maximum allowable prescaler output frequency of 750 MHz. It utilizes a 3-wire serial interface for configuration.

Feature Summary

• Fast settling architecture enabling GSM band frequency hopping in 5 μs with phase settled within 20 μs
• Low phase noise performance with a figure of merit of -216 dBc/Hz and 1 degree rms phase error at 4 GHz
• Integrated on-chip low noise differential amplifier converting differential charge pump output to single-ended voltage
• Digitally programmable output phase via 3-wire serial interface

Applications

• GSM/EDGE base stations
• PHS base stations
• Pulse Doppler radar systems
• Instrumentation and test equipment
• Beam-forming/phased array systems

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging format as indicated in the manufacturer's part number structure. Confirm that the LFCSP-32 package requires proper thermal management given the junction temperature rating. Ensure compatibility with the required external loop filter and VCO components for the intended application bandwidth.

Selection Notes

Select this component when designing local oscillators for wireless receivers and transmitters requiring fast lock times to replace ping-pong synthesizers. The device is suitable for applications needing a single PLL solution for GSM/EDGE lock time requirements. Consider the 6 GHz RF input limit and the need for external VCO and loop filter components to complete the phase-locked loop implementation.

Part Context

The ADF4196BCPZ-RL7 belongs to the ADF4196 family of PLL frequency synthesizers from Analog Devices. It is designed to simplify designs for communication infrastructure and radar applications by eliminating the complexity associated with dual-PLL architectures. The device integrates sigma-delta based fractional interpolation and a programmable modulus fractional-N division capability.
