ADF4107BCPZ-REEL

Overview

The ADF4107BCPZ-REEL is an Integer-N PLL frequency synthesizer manufactured by Analog Devices Inc. It operates with a 7.0 GHz bandwidth and supports power supplies from 2.7 V to 3.3 V, featuring a separate charge pump supply (VP) for extended tuning voltage up to 5.5 V. The device includes a programmable dual-modulus prescaler (8/9, 16/17, 32/33, 64/65), programmable charge pump currents, and a 3-wire serial interface. It consumes 17 mA at 3 V and is housed in a 20-lead LFCSP package.

Feature Summary

• 7.0 GHz RF input bandwidth with 1.0 GHz to 7.0 GHz operating range
• Programmable dual-modulus prescaler options: 8/9, 16/17, 32/33, 64/65
• Separate VP pin allows charge pump supply up to 5.5 V for extended VCO tuning
• Integrated digital and analog lock detect functions

Applications

• Broadband wireless access systems
• Satellite communication systems
• Wireless LAN local oscillators
• Base stations for wireless radio
• LMDS base station transmitters

Procurement Notes

Verify the specific suffix REEL indicates reel packaging when sourcing. Confirm the B version temperature range of -40°C to +85°C matches application requirements. Ensure the LFCSP-20 package footprint aligns with PCB design guidelines provided in the datasheet. Check for moisture sensitivity handling requirements during assembly.

Selection Notes

Select this component for applications requiring high bandwidth integer-N synthesis up to 7 GHz. The separate VP supply is critical if the system requires VCO tuning voltages exceeding the 3.3 V logic supply. Verify that the chosen prescaler division ratio (P) keeps the prescaler output below 300 MHz for the target RF frequency.

Part Context

This part belongs to the ADF4107 series of PLL frequency synthesizers. The B variant specifies the industrial temperature grade (-40°C to +85°C). The REEL suffix denotes tape-and-reel packaging for automated surface-mount assembly. It is distinct from the BRU variants which use TSSOP packages.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate other members of the ADF410x family or ADF415x series based on required bandwidth and noise specifications.
