ADF4355BCPZ

Overview

The ADF4355BCPZ 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) architectures, enabling operation across an RF output frequency range of 54 MHz to 6800 MHz. The device features a high-resolution 38-bit modulus for precise frequency synthesis. Power supplies include analog and digital rails at 3.15 V to 3.45 V, and charge pump/VCO supplies at 4.75 V to 5.25 V. It operates within a temperature range of -40°C to +85°C and utilizes a 3-wire serial interface for register control.

Feature Summary

• Integrated VCO with fundamental output frequency ranging from 3400 MHz to 6800 MHz
• Programmable output dividers allowing division by 1, 2, 4, 8, 16, 32, or 64
• Low phase noise performance with normalized in-band floor of -221 dBc/Hz (fractional) and -223 dBc/Hz (integer)
• RF output mute function controllable via pin or software

Applications

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

Procurement Notes

Verify the specific suffix BCPZ corresponds to the 32-LFCSP package variant when sourcing. Confirm that the ordering information aligns with the manufacturer's current data sheet revision to ensure compatibility with design requirements. Cross-reference pinout details with official documentation prior to PCB layout.

Selection Notes

Select this component for applications requiring wide bandwidth up to 6.8 GHz with low phase noise. Ensure the external loop filter design accommodates the programmable charge pump current range of 0.3 mA to 4.8 mA. Verify that the reference input frequency matches the supported single-ended (up to 250 MHz) or differential (up to 600 MHz) modes.
