ADF5356BCPZ

Overview

The ADF5356BCPZ 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 53.125 MHz to 13,600 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 outputs. Key electrical parameters include analog and digital power supplies of 3.15 V to 3.45 V, charge pump and VCO supplies of 4.75 V to 5.25 V, and a maximum reference input frequency of 600 MHz in differential mode. It operates within a temperature range of −40°C to +85°C.

Feature Summary

• Wideband operation from 53.125 MHz to 13,600 MHz with integrated VCO
• Low noise floor: −227 dBc/Hz for integer channels and −225 dBc/Hz for fractional channels
• Integrated RMS jitter of 97 fs measured at 6 GHz output (1 kHz to 20 MHz offset)
• Pin-compatible upgrade to the ADF5355 with 52-bit modulus resolution

Applications

• Wireless infrastructure including LTE, W-CDMA, TD-SCDMA, WiMAX, GSM, PCS, and DCS
• Point-to-point and point-to-multipoint microwave links
• Satellites and very small aperture terminals (VSATs)
• Test equipment and instrumentation requiring precise clock generation

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm package integrity for the LFCSP-32 form factor prior to assembly. Ensure compliance with RoHS directives as specified in official documentation. Review product change notifications for any revisions affecting pinout or electrical characteristics before finalizing procurement plans.

Selection Notes

Select the ADF5356BCPZ when applications require high-frequency synthesis up to 13.6 GHz with low phase noise. Ensure external loop filter design accommodates the charge pump current range of 0.3 mA to 4.8 mA. Verify that system power rails can provide stable 3.3 V for logic/analog and 5.0 V for VCO/charge pump sections. Consider the ADIsimPLL tool for optimizing loop bandwidth and jitter performance.

Part Context

The ADF5356 serves as a direct pin-compatible upgrade to the ADF5355, offering extended frequency coverage up to 13.6 GHz compared to the previous model's limits. It belongs to the ADF5356 family of microwave wideband synthesizers. The device integrates a wideband VCO and multiple output dividers, reducing the need for external frequency multiplication stages in high-frequency designs.

Replacement Considerations

The ADF5355 is a compatible predecessor with identical pinouts but lower maximum frequency specifications. Designers upgrading from ADF5355 should verify that existing loop filters support the wider tuning range and updated charge pump characteristics of the ADF5356.
