ADF4218BRU-REEL

Overview

The ADF4218BRU-REEL is an Integer-N Phase-Locked Loop (PLL) manufactured by Analog Devices Inc. It operates within a frequency range of 500 MHz to 2500 MHz and features low power consumption. The device supports dual circuits and accepts input frequencies between 10 MHz and 3 GHz. It functions on a supply voltage ranging from 2.6 V to 3.3 V, with a typical operating current of 7 mA. The component is housed in a TSSOP-20 surface-mount package and is rated for operation between -40°C and +85°C.

Feature Summary

• Dual-circuit Integer-N PLL architecture
• Frequency range: 500 MHz to 2500 MHz
• Low power consumption: 7 mA typical
• Input frequency support: 10 MHz to 3 GHz

Applications

• Wireless communication systems
• RF signal generation
• Frequency synthesis in test equipment

Procurement Notes

Verify the specific suffix 'REEL' against official Analog Devices documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with the required TSSOP-20 footprint and thermal management requirements for the -40°C to +85°C operating range. Cross-reference the manufacturer part number with authorized distributors to confirm current availability status.

Selection Notes

Select this component when a dual-circuit Integer-N PLL is required for frequencies up to 2.5 GHz. Verify that the system power supply aligns with the 2.6 V to 3.3 V operating range. Confirm that the TSSOP-20 package size fits the PCB layout constraints. Compare input frequency requirements against the 10 MHz to 3 GHz specification to ensure proper operation.

Part Context

This part belongs to the ADF4218L series of low-power PLLs from Analog Devices. It shares architectural similarities with other members like the ADF4118 but offers dual circuit capability. The 'BRU' indicates the commercial temperature grade and TSSOP-20 package, while '-REEL' specifies the reel packaging format for automated assembly.

Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio. Verify if single-circuit PLLs like the ADF4118 meet the design needs if dual circuits are not utilized. Ensure any substitute maintains the same Integer-N topology and frequency coverage.
