ADF4001BCPZ-RL7

Overview

The ADF4001BCPZ-RL7 is an Integer-N clock generator PLL from Analog Devices, packaged in a 20-lead LFCSP. It operates on a 2.7 V to 5.5 V supply with a typical current of 4.5 mA. The device supports RF input frequencies up to 200 MHz and reference inputs up to 104 MHz. Key electrical parameters include a phase detector frequency limit of 55 MHz, programmable charge pump currents ranging from 625 µA to 5 mA, and an ultralow phase noise floor of –161 dBc/Hz at 200 kHz offset. It features a 3-wire serial interface, hardware/software power-down modes, and analog/digital lock detect capabilities.

Feature Summary

• Ultralow phase noise performance with a floor of –161 dBc/Hz typ at 200 kHz PFD frequency
• Programmable charge pump currents via CPI bits, supporting high value (5 mA typ) and low value (625 µA typ)
• Separate charge pump supply (VP) allows extended tuning voltage up to 6.0 V in 5 V systems
• Hardware compatible with ADF4110/ADF4111/ADF4112/ADF4113 families

Applications

• Clock generation for low jitter applications
• Low frequency PLL implementations
• SONET, ATM, ADM, DSLAM, SDM systems
• Frequency translation circuits

Procurement Notes

Verify the B version suffix indicates the industrial temperature range of –40 °C to +85 °C. Confirm the RL7 suffix corresponds to the reel packaging format. Ensure compatibility with the EV-ADF4001SD1Z development kit if evaluation is required. Check for moisture sensitivity labeling as indicated in distributor specifications.

Selection Notes

Select this component when implementing integer-N synthesis requiring minimal phase noise. The separate VP pin is critical for driving VCOs with tuning ranges exceeding the AVDD level. Ensure the external RSET resistor is within the 2.7 kΩ to 10 kΩ range to set the desired maximum charge pump current accurately.

Part Context

This part belongs to the ADF4001 family, which also includes the 16-lead TSSOP variant (ADF4001BRUZ). The BCPZ package denotes the 20-lead Low Profile Leadless Chip Package. The device serves as a core synthesizer element, requiring external loop filters and VCOs/VCXOs to complete the PLL architecture.

Replacement Considerations

The ADF4001BRUZ is a direct functional substitute with identical electrical characteristics but utilizes a 16-lead TSSOP package instead of the LFCSP-20. Verify footprint compatibility before substitution.
