ADF4355-2BCPZ-RL7

Overview

The ADF4355-2BCPZ-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) frequency synthesis, covering an RF output range from 54 MHz to 4400 MHz. The device features a fundamental VCO operating between 3400 MHz and 6800 MHz, with programmable divide-by-1, 2, 4, 8, 16, 32, or 64 output dividers. It utilizes a 3-wire serial interface for register control and operates on separate analog/digital supplies of 3.15 V to 3.45 V and charge pump/VCO supplies of 4.75 V to 5.25 V.

Feature Summary

• Integrated low-noise VCO with fundamental frequency range of 3400 MHz to 6800 MHz
• Fractional-N and integer-N synthesizer capabilities with high resolution 38-bit modulus
• Programmable output dividers (÷1, ÷2, ÷4, ÷8, ÷16, ÷32, ÷64) enabling outputs down to 54 MHz
• Dual supply architecture: 3.3 V for logic/analog and 5 V for charge pump/VCO

Applications

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

Procurement Notes

Verify the specific ordering suffix BCPZ-RL7 against the manufacturer's current data sheet to confirm package type and reel quantity specifications. Ensure that the required power supply rails match the device's dual-voltage requirements of 3.3 V and 5 V before integration into the design.

Selection Notes

Select this component when applications require a wide tuning range up to 4.4 GHz with integrated VCO performance. Designers must account for the separate 5 V supply requirement for the charge pump and VCO, distinct from the 3.3 V digital and analog supplies. Verify that the external reference input supports the desired PFD frequency within the specified limits.

Part Context

The ADF4355-2 belongs to the ADF4355 family of microwave wideband synthesizers. This series is designed for high-performance RF applications requiring low phase noise and flexible frequency synthesis options. The device integrates the VCO and PLL circuitry to minimize external component count while maintaining signal integrity across a broad frequency spectrum.
