ADF4107BCP

Overview

The ADF4107BCP is an Integer-N PLL frequency synthesizer designed for local oscillator implementation in wireless transceivers. It features a 7.0 GHz bandwidth, supporting RF input frequencies from 1.0 GHz to 7.0 GHz with -5/+5 dBm sensitivity. Powered by 2.7 V to 3.3 V supplies (AVDD/DVDD) and a separate charge pump supply (VP), it draws 17 mA typical current. The device integrates a low-noise digital PFD, precision charge pump, programmable reference divider, dual-modulus prescaler (8/9, 16/17, 32/33, 64/65), and 3-wire serial interface. It operates within -40°C to +85°C.

Feature Summary

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

Applications

• Broadband wireless access systems
• Satellite communication systems
• Wireless LAN infrastructure
• Base stations for wireless radio
• General instrumentation requiring frequency synthesis

Procurement Notes

Verify the specific package suffix against the ordering guide, as B version chips are available in TSSOP-16 and LFCSP-20 packages. Confirm RoHS compliance status for the specific revision. Check for discontinuance notices or PCNs regarding assembly relocation to STATS ChipPAC facilities. Ensure ESD precautions are observed during handling due to the high-performance RF nature of the component.

Selection Notes

Select the appropriate prescaler value (P) based on the target RF frequency to ensure the prescaler output remains below 300 MHz. For example, at 4.0 GHz, a 16/17 prescaler is valid, whereas 8/9 is not. Ensure the RSET resistor value matches the desired charge pump current, typically 5.1 kΩ for 5 mA max current. Verify that the VP supply voltage accommodates the external VCO tuning requirements if extended voltage is needed beyond the 3.3 V logic level.

Part Context

The ADF4107 belongs to Analog Devices' family of integer-N PLL synthesizers. It is functionally similar to the ADF4007 but offers higher bandwidth and different prescaler configurations. The B version denotes industrial temperature range operation (-40°C to +85°C). The device eliminates the need for frequency doublers in many high-frequency systems due to its wide bandwidth, simplifying system architecture.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. Designers should consult the manufacturer's official documentation for cross-reference recommendations or updated product line replacements.
