ADF41510BCPZ

Overview

The ADF41510BCPZ is a high-performance silicon germanium (SiGe) BiCMOS integer-N/fractional-N PLL synthesizer designed for local oscillator generation up to 10 GHz. It features an ultra-low normalized phase noise floor of −235 dBc/Hz in integer-N mode and −231 dBc/Hz in fractional-N mode. The device supports a maximum PFD frequency of 250 MHz for integer-N and 125 MHz for fractional-N operation. It includes a programmable charge pump with a 16× current range, integrated 1.8 V logic capability, and a digital lock detect output. The component operates on a single 3.3 V supply and is housed in a compact 24-lead, 4 mm × 4 mm LFCSP package.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and reel specifications. Ensure that the procurement channel provides valid traceability for this Analog Devices component. Confirm availability status directly with authorized distributors as stock levels fluctuate. Check for any recent product change notifications regarding assembly relocation or material updates before placing orders.

Selection Notes

Select the ADF41510BCPZ when designing systems requiring local oscillators up to 10 GHz with stringent phase noise requirements. Choose the 25-bit fixed modulus for subhertz resolution or the 49-bit variable modulus for exact frequency synthesis. Ensure the external VCO and loop filter are compatible with the device's RF input sensitivity and charge pump current capabilities. Verify that the system architecture can accommodate the required 3.3 V power supply and thermal management for the LFCSP package.

Part Context

The ADF41510 belongs to Analog Devices' family of high-performance PLL frequency synthesizers. It serves as a successor or alternative to earlier models like the ADF4151, offering improved phase noise performance and higher PFD frequencies. The device is part of the broader portfolio used in RF front-end designs, complementing other synthesizers such as the ADF4351 and ADF4360 series which may target different frequency ranges or integration levels.
