ADF4001BRUZ

Overview

The ADF4001BRUZ is a 200 MHz clock generator PLL manufactured by Analog Devices Inc. It features a low-noise digital phase frequency detector, precision charge pump, programmable reference divider, and a 13-bit N counter. The device supports a 14-bit R counter for selectable input frequencies and operates on a 2.7 V to 5.5 V power supply with a typical current of 4.5 mA. It utilizes a 3-wire serial interface and includes hardware/software power-down modes. The component is housed in a 16-lead TSSOP package.

Feature Summary

• Ultralow phase noise performance with a floor of -161 dBc/Hz at 200 kHz offset
• Programmable charge pump currents with two distinct settings for dynamic loop bandwidth control
• Separate charge pump supply (VP) allows extended tuning voltage up to 6.0 V in 5 V systems
• Hardware compatible with the ADF4110/ADF4111/ADF4112/ADF4113 families

Applications

• Clock generation for stable reference signals
• Low jitter clock source implementation
• SONET, ATM, ADM, DSLAM, SDM systems
• Frequency translation applications

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging type. The BRUZ suffix indicates a tube package variant. Confirm RoHS compliance status through the manufacturer's latest certification documents before procurement.

Selection Notes

Select this component when implementing integer-N PLLs requiring ultralow phase noise. Ensure the external VCO or VCXO tuning range is compatible with the separate VP supply capability. Verify that the required PFD frequency does not exceed the 55 MHz maximum limit.

Part Context

The ADF4001BRUZ belongs to the ADF4001 family of clock generators. It serves as a core synthesizer component for generating stable reference signals in communication infrastructure equipment. The device integrates essential PLL functions into a single chip to reduce system complexity.

Replacement Considerations

The datasheet notes hardware compatibility with the ADF4110, ADF4111, ADF4112, and ADF4113. These parts share functional similarities but may have different pinouts or electrical specifications. Verify register compatibility and pin mapping before substitution.
