ADF4001BRU-REEL7

Overview

The ADF4001BRU-REEL7 is a 200 MHz clock generator PLL in a 16-lead TSSOP package. It integrates a low-noise digital phase frequency detector, precision charge pump, programmable reference divider, and 13-bit N counter. The device supports 2.7 V to 5.5 V power supplies with a separate VP pin for extended tuning voltage up to 6.0 V. Typical operating current is 4.5 mA. It features ultralow phase noise, hardware/software power-down modes, and analog/digital lock detect capabilities.

Feature Summary

• 200 MHz bandwidth with ultralow phase noise performance
• Separate charge pump supply (VP) allows extended tuning voltage in 5 V systems
• Programmable charge pump currents via 3-wire serial interface
• Hardware compatible with ADF4110/ADF4111/ADF4112/ADF4113

Applications

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

Procurement Notes

Verify the B version suffix indicates an industrial temperature range of -40°C to +85°C. Confirm the REEL7 suffix corresponds to tape and reel packaging containing 1000 units. Ensure the order matches the specific Analog Devices part number ADF4001BRU-REEL7 to guarantee correct package type and electrical specifications.

Selection Notes

Select this component when implementing PLLs that require very low noise and stable reference signals. The device requires an external loop filter and VCO or VCXO to form a complete synthesizer. Consider the separate VP supply if the system requires tuning voltages exceeding the AVDD level. Verify compatibility with existing ADF411x family designs if migration is planned.

Part Context

The ADF4001 is part of Analog Devices' clock generator PLL family. It is designed to provide flexible clock sources for communication systems. The BRU variant specifically denotes the 16-lead TSSOP package option. This component serves as a core building block for generating precise frequencies in data converters and RF systems.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The datasheet notes hardware compatibility with the ADF4110, ADF4111, ADF4112, and ADF4113 families, but these are distinct components with different feature sets and should be evaluated individually for direct replacement.
