ADF5610BCCZ

Overview

The ADF5610BCCZ is a microwave wideband synthesizer with an integrated voltage-controlled oscillator (VCO) and fractional-N or integer-N phase-locked loop (PLL). It operates from 57 MHz to 14,600 MHz. The RFOUT output covers 7300 MHz to 14,600 MHz with a typical power of 5 dBm. Differential outputs (PDIV_OUT/NDIV_OUT) provide frequencies from 57 MHz to 14,600 MHz. The device features low phase noise, typically −115 dBc/Hz at 100 kHz offset for 7.3 GHz operation. Power dissipation is typically 815 mW, with a programmable low-current mode under 700 mW. It uses a 48-terminal, 7 mm × 7 mm LGA package.

Feature Summary

• Integrated VCO and PLL supporting fractional-N and integer-N modes with a 24-bit fractional modulus.
• RF output frequency range of 57 MHz to 14,600 MHz with programmable divide-by-1, 2, 4, 8, 16, 32, 64, or 128 outputs.
• Low phase noise performance: −115 dBc/Hz typical at 100 kHz offset (7.3 GHz), −114 dBc/Hz at 10 GHz, and −109 dBc/Hz at 14.6 GHz.
• Fast frequency hopping capability with autocalibration enabled in less than 40 µs.

Applications

• Military and defense systems
• Test equipment
• Clock generation
• Wireless infrastructure
• Satellite and very small aperture terminal (VSAT)
• Microwave radio

Procurement Notes

Verify the ordering suffix BCCZ corresponds to the standard tape-and-reel or tray packaging configuration specified by Analog Devices for this part number. Confirm that the component meets RoHS compliance standards as indicated in the manufacturer's documentation. Ensure the supply chain source provides valid traceability for the 7 mm × 7 mm LGA package variant.

Selection Notes

Select the ADF5610BCCZ when a single-chip solution covering 57 MHz to 14.6 GHz is required. The device supports both high-performance and low-power modes, allowing optimization of current consumption versus phase noise. Use the exact frequency mode for zero Hz frequency error applications. Ensure external loop filter design accommodates the charge pump current settings and desired loop bandwidth for optimal lock time.

Part Context

The ADF5610BCCZ belongs to the ADF5610 family of microwave wideband synthesizers. It integrates a broadband VCO with a fractional-N/integer-N PLL on a single chip. This integration reduces system size and complexity compared to discrete solutions using separate VCOs and PLLs. The device is designed for high-frequency applications requiring low phase noise and fast tuning speeds.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices for alternative components within the same product family or similar specifications if the ADF5610BCCZ is unavailable.

FAQ

What is the maximum SPI clock speed for the ADF5610?

The maximum serial clock (SCK) frequency rate is 50 MHz in CMOS mode and 10 MHz in open-drain mode.

How does the ADF5610 achieve fast frequency hopping?

Fast frequency hopping is achieved through autocalibration, which allows the device to hop frequencies in less than 40 µs.

What are the power supply requirements for the ADF5610?

The analog and digital supplies (AVDD, DVDD, etc.) require 3.1 V to 3.5 V, while the VCO supply (VCOVCC) requires 4.75 V to 5.25 V.
