Overview
The MAX2450CEP+ is a monolithic integrated circuit combining a quadrature modulator and a quadrature demodulator. It includes a supporting oscillator and a divide-by-8 prescaler. The device operates within the 70 MHz to 160 MHz frequency range. It utilizes Silicon technology and is housed in an SSOP-20 package with a 150mil body width. The component supports a wide operating temperature range from -40°C to +85°C.
Feature Summary
- Integrates quadrature modulation and demodulation functions on a single chip
- Includes an internal oscillator and divide-by-8 prescaler for signal processing
- Designed for RF applications requiring precise phase modulation and demodulation
Applications
- Wireless networking systems
- RF communication transceivers
- Embedded wireless modules
Procurement Notes
Verify current availability status as the MAX2450CEP-W variant is listed as discontinued or restricted in some regions. Confirm package integrity and lead times with authorized distributors. Ensure compatibility with existing design specifications before procurement, as supply chain constraints may affect delivery schedules for this legacy component.
Selection Notes
Select this component for designs requiring integrated quadrature modulation and demodulation in the 70-160 MHz band. Consider the SSOP-20 package size for PCB layout constraints. Verify that the internal oscillator and prescaler meet system timing requirements without external components. Evaluate thermal performance within the specified -40°C to +85°C operating range.
Part Context
The MAX2450 belongs to the Maxim Integrated family of RF modems. It serves as a complete solution for generating and detecting quadrature signals. The device simplifies RF front-end design by integrating multiple functions typically requiring separate components. It is suitable for cost-sensitive wireless applications requiring reliable modulation performance.
Replacement Considerations
Check for direct pin-compatible substitutes if the MAX2450CEP+ is unavailable. Review datasheets for alternative quadrature modems with similar frequency ranges and integration levels. Ensure any replacement maintains compatibility with the system's oscillator and prescaler requirements.
