ADF4106BCPZ-RL

Overview

The ADF4106BCPZ-RL is a PLL frequency synthesizer from Analog Devices Inc., packaged in a 20-lead LFCSP_WQ. It operates on a 2.7 V to 3.3 V supply with a maximum input frequency of 6.0 GHz and an output range up to 325 MHz. The device features a low-noise digital phase frequency detector, programmable charge pump currents, and a dual-modulus prescaler (8/9, 16/17, 32/33, 64/65). It includes a 3-wire serial interface, analog/digital lock detect, and power-down modes. The industrial temperature range is -40°C to +85°C.

Feature Summary

• 6.0 GHz bandwidth with integrated dual-modulus prescaler
• Programmable charge pump currents and antibacklash pulse width
• Separate VP supply for extended tuning voltage in 3 V systems
• 3-wire serial interface with hardware/software power-down

Applications

• Broadband wireless access
• Satellite systems
• Instrumentation
• Wireless LANs
• Base stations for wireless radios

Procurement Notes

Verify the B version suffix indicates the -40°C to +85°C operating range. Confirm the LFCSP_WQ package requires soldering the exposed paddle to AGND. Check for humidity sensitivity handling requirements during assembly. Ensure the REEL packaging format matches production line specifications.

Selection Notes

Select this component when a 6 GHz synthesizer with high integration is required. The separate VP pin allows tuning voltages up to 5.5 V even with a 3 V logic supply. Verify that the external VCO can be driven by the available charge pump current. Ensure the reference frequency falls within the 20 MHz to 300 MHz range.

Part Context

This part belongs to the ADF4106 family of integer-N PLL synthesizers. The BCPZ variant denotes the commercial grade LFCSP package. The -RL suffix indicates tape and reel packaging. It serves as a local oscillator source for up-conversion and down-conversion sections in RF transceivers.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the verified documentation.
