ADF5355BCPZ

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) frequency synthesis, covering an RF output range from 54 MHz to 13,600 MHz. The device features a high-resolution 38-bit modulus and a programmable dual modulus prescaler of 4/5 or 8/9. It operates with analog and digital power supplies at 3.3 V and charge pump/VCO supplies at 5.0 V typical. The component maintains frequency lock over an operating temperature range of −40°C to +85°C.

Feature Summary

• Integrated VCO with fundamental frequency range of 3400 MHz to 6800 MHz
• Programmable divide-by-1, 2, 4, 8, 16, 32, or 64 output dividers
• Phase frequency detector (PFD) operation up to 125 MHz
• Reference frequency operation up to 600 MHz

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

Procurement Notes

Verify the specific ordering suffix RL7 against the manufacturer's current documentation to confirm reel packaging specifications. Ensure that the required external components, such as the loop filter and reference clock source, are compatible with the device's electrical requirements before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a single-chip solution for broadband frequency synthesis up to 13.6 GHz. Consider the 3-wire serial interface compatibility and the need for separate 3.3 V and 5.0 V power rails when designing the system architecture. Evaluate the integrated VCO noise performance against application-specific phase noise requirements.

Part Context

The ADF5355 belongs to the ADF5355 series of microwave wideband synthesizers. It is designed to replace discrete PLL and VCO solutions in RF and microwave communication systems. The device integrates a low phase noise VCO and a high-performance fractional-N synthesizer into a single chip-scale package.
