ADF4107BCP-REEL7

Overview

The ADF4107BCP-REEL7 is an Integer-N PLL frequency synthesizer from Analog Devices, designed for local oscillator implementation in wireless receivers and transmitters. It features a low-noise digital phase-frequency detector, precision charge pump, programmable reference divider, and dual-modulus prescaler (8/9, 16/17, 32/33, 64/65). The device operates with AVDD/DVDD between 2.7 V and 3.3 V, while the separate VP supply allows extended tuning voltage up to 5.5 V. It supports RF input frequencies from 1.0 GHz to 7.0 GHz and includes a 3-wire serial interface, hardware/software power-down modes, and analog/digital lock detect capabilities.

Feature Summary

• Operates within a 1.0 GHz to 7.0 GHz RF input frequency range
• Supports 2.7 V to 3.3 V logic supplies with a separate VP pin for up to 5.5 V charge pump bias
• Features a programmable dual-modulus prescaler with options of 8/9, 16/17, 32/33, or 64/65
• Includes a 14-bit R counter and N divider architecture (N = BP + A) for flexible frequency synthesis

Applications

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

Procurement Notes

Verify that the specific ordering suffix corresponds to the LFCSP package variant rather than the TSSOP version. Confirm RoHS compliance status as specifications may vary by manufacturing revision. Ensure the component meets the required industrial temperature range of -40°C to +85°C for the B version. Check for any end-of-life notices or discontinuance updates from the manufacturer prior to finalizing procurement plans.

Selection Notes

Select this component when a high-bandwidth synthesizer is needed to eliminate external frequency doublers in high-frequency systems. Ensure the design accommodates the separate VP supply rail if higher VCO tuning voltages are required. Verify that the maximum PFD frequency of 104 MHz aligns with the system's reference clock requirements. Consider the LFCSP thermal impedance of 30.4°C/W for adequate PCB heat dissipation during operation.

Part Context

This part belongs to the ADF4107 family of frequency synthesizers manufactured by Analog Devices. It is functionally similar to other members like the ADF4107BRU but differs in packaging, specifically utilizing the LFCSP form factor. The device integrates essential PLL components into a single chip to simplify system architecture and reduce overall cost compared to discrete solutions.
