ADF4001BRUZ-RL

Overview

The ADF4001BRUZ-RL is an Integer-N clock generator PLL from Analog Devices, housed in a 16-lead TSSOP package. It operates on a 2.7 V to 5.5 V supply with a typical current of 4.5 mA. The device features a 13-bit N counter and a 14-bit R counter, supporting input frequencies up to 200 MHz at 5 V. Key specifications include programmable charge pump currents (up to 5 mA typ), ultralow phase noise (-161 dBc/Hz typ at 200 kHz offset), and hardware/software power-down modes. It utilizes a 3-wire serial interface for configuration.

Feature Summary

• Ultralow phase noise floor of -161 dBc/Hz at 200 kHz PFD frequency
• Programmable charge pump currents ranging from 0.625 mA to 5 mA typ
• Separate VP supply pin allows extended tuning voltage up to 6.0 V
• Hardware compatible with ADF4110/ADF4111/ADF4112/ADF4113 families

Applications

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

Procurement Notes

Verify the suffix '-RL' indicates reel packaging when sourcing. Confirm the 'B' version temperature range is -40°C to +85°C. Ensure the order includes the specific Analog Devices part number ADF4001BRUZ-RL to match the TSSOP-16 package and electrical specifications provided in the datasheet.

Selection Notes

Select this component for designs requiring stable reference signals with minimal phase noise. The separate VP supply is advantageous for driving VCOs with higher tuning ranges in 5 V systems. Ensure the external loop filter and VCO are compatible with the programmable charge pump currents and the 200 MHz maximum bandwidth.

Part Context

This part belongs to the ADF4001 family of clock generators. It is functionally similar to the ADF4002 but optimized for specific bandwidth and noise characteristics. The BRUZ designation confirms the industrial temperature grade and TSSOP-16 surface mount package.

Replacement Considerations

The ADF4001 is hardware compatible with the ADF4110, ADF4111, ADF4112, and ADF4113. These parts may serve as direct replacements if their specific electrical parameters meet the design requirements.
