ADF5355BCPZ-RL7

Overview

The ADF5355BCPZ-RL7 is a microwave wideband synthesizer with an integrated voltage-controlled oscillator (VCO), manufactured by Analog Devices Inc. It supports fractional-N and integer-N phase-locked loop (PLL) configurations when used with an external loop filter and reference frequency. The device operates over an RF output frequency range of 54 MHz to 13,600 MHz. Key electrical parameters include analog and digital power supplies of 3.15 V to 3.45 V, and charge pump/VCO supplies of 4.75 V to 5.25 V. It features a high-resolution 38-bit modulus, programmable output dividers, and low phase noise performance.

Feature Summary

• RF output frequency range from 54 MHz to 13,600 MHz
• Integrated VCO with fundamental frequency range of 3400 MHz to 6800 MHz
• Supports both fractional-N and integer-N PLL architectures
• Programmable output dividers: divide by 1, 2, 4, 8, 16, 32, or 64

Applications

• Wireless infrastructure including W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, DCS, and DECT
• Point-to-point and point-to-multipoint microwave links
• Satellites and VSAT systems
• Test equipment and instrumentation
• Clock generation applications

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration as indicated in distributor listings. Confirm that the LFCSP-32 package requires appropriate PCB design guidelines for chip-scale packages, particularly regarding the exposed pad connection to AGND. Ensure supply voltages match the specified ranges for AVDD/DVDD and VP/VVCO during procurement planning.

Selection Notes

Select this component for applications requiring wideband synthesis up to 13.6 GHz with integrated VCO functionality. Consider the separate power supply requirements for analog/digital sections (3.3 V typical) versus charge pump/VCO sections (5.0 V typical). Evaluate the need for external loop filters and reference frequencies, as these are not included on-chip. Check compatibility with ADIsimPLL design tool for parameter optimization.

Part Context

The ADF5355 belongs to the ADF5355 series of microwave wideband synthesizers. It is part of Analog Devices' interactive RF signal chain portfolio, often grouped with similar devices like the ADF4355/56. The BC part number variant typically denotes a specific temperature grade or package revision within the standard ADF5355 family, housed in a 32-LFCSP package.

Replacement Considerations

The ADF5356 is documented as an upgrade to the ADF5355, offering similar functionality with a maximum output frequency of 13.6 GHz. Both devices share the LFCSP-32 package form factor. Verify register compatibility and pinout equivalence before substituting, as the ADF5356 may have updated specifications or features.
