ADF4007BCPZ-RL7

Overview

The ADF4007BCPZ-RL7 is a high-frequency divider and PLL synthesizer from Analog Devices, housed in a 20-lead Lead Frame Chip Scale Package (CP-20-6). It supports RF input frequencies up to 7.5 GHz and a maximum Phase Frequency Detector (PFD) frequency of 120 MHz. The device operates on a 2.7 V to 3.3 V supply with a separate charge pump supply (VP) extending up to 5.5 V for enhanced tuning voltage capabilities. Key electrical parameters include a typical charge pump current of 5.0 mA with an RSET of 5.1 kΩ, a normalized phase noise floor of −219 dBc/Hz, and a total operating current of 15 mA typ at 3 V. The N counter divider ratio is programmable via hardware pins to 8, 16, 32, or 64.

Feature Summary

• Operates with RF input frequencies ranging from 0.5 GHz to 7.5 GHz and PFD frequencies up to 120 MHz.
• Features a precision charge pump with adjustable current controlled by an external RSET resistor (typical ICP = 5.0 mA at 5.1 kΩ).
• Includes a hardware-configurable prescaler with divide ratios of 8, 16, 32, or 64 selected via N1/N2 pins.
• Provides a multiplexer output (MUXOUT) accessible via M1/M2 pins to monitor internal divider states.

Applications

• Satellite communications systems requiring high-frequency local oscillators.
• Broadband wireless access infrastructure.
• CATV (Cable Television) signal processing.
• Wireless LANs and instrumentation.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's guide to confirm packaging type. The ADF4007BCPZ-RL7 designation indicates a reel package configuration within the CP-20-6 footprint. Ensure that procurement specifications align with the industrial temperature range of −40°C to +85°C defined for the B version. Confirm RoHS compliance status as indicated by the Z suffix in the base part number.

Selection Notes

Select this component when system architecture requires direct synthesis up to 7.5 GHz without intermediate frequency doublers. The separate VP pin allows operation with VCOs requiring tuning voltages higher than the 3.3 V logic supply. Ensure the reference input frequency does not exceed 240 MHz due to the fixed R-counter division of 2. Verify that the required N-divider value corresponds to one of the four discrete hardware settings (8, 16, 32, 64).

Part Context

The ADF4007BCPZ-RL7 belongs to the ADF4007 family of high-frequency PLL synthesizers. It shares the same core functionality and pinout with the ADF4007BCPZ and ADF4007BCPZ-RL variants, differing primarily in shipping packaging. The device integrates a low-noise digital PFD, a precision charge pump, and a high-speed prescaler into a single compact chip-scale package.

Replacement Considerations

Public documentation identifies the HMC1031MS8ETR as a discontinued alternative. No other verified public substitute part numbers are listed for the ADF4007BCPZ-RL7 in the provided source material.
