Overview
The MAX2623EUA+ is a monolithic voltage-controlled oscillator (VCO) manufactured by Analog Devices under the Maxim Integrated brand. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an oscillator frequency range from 885 MHz to 950 MHz. The device features low current shutdown capability and functions across an operating temperature range of -40°C to +85°C. Packaged in an 8-MSOP (uMAX-8) format, it integrates RF oscillator functionality suitable for mixed-signal applications.
Feature Summary
- Monolithic integration of voltage-controlled oscillator circuitry
- Low current shutdown mode for power management
- Wide operating temperature range supporting industrial environments
Applications
- RF transmitters requiring out-of-range alarm functionality
- Wireless Local Loop (WLL) systems operating near 3.5 GHz
- Mixed-signal PCB designs involving RF components
Procurement Notes
Verify the specific package variant, as sources indicate both MSOP-8 and TSSOP configurations exist for this part number. Confirm RoHS compliance status through official documentation before procurement. Ensure the supplier provides the correct datasheet version matching the intended frequency and voltage specifications.
Selection Notes
Select this component when a compact, monolithic VCO solution is required for frequencies between 885 MHz and 950 MHz. Consider the 2.7 V to 5.5 V supply range compatibility with existing system power rails. Evaluate the low current shutdown feature against system power efficiency requirements.
Part Context
This component belongs to the Maxim Integrated RF oscillator family, designed for wireless communication applications. It serves as a key element in RF transmitter chains, providing stable frequency generation. The device complements other RF ICs used in WLL and similar wireless infrastructure projects.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Verify pinout and electrical parameters with alternative VCOs if substitution is necessary.
