- Tire Pressure Monitoring Systems (TPMS)
- Wireless security systems
- Low-power telemetry applications
- Garage door openers
Features:
- Low power consumption
- Single conversion FM receiver
- Operating frequency: 300MHz to 450MHz
- Integrated local oscillator with crystal oscillator
- RSSI (Received Signal Strength Indicator) output
- Data slicer with adjustable threshold
- Low external component count
Benefits:
- Extended battery life in portable devices
- Compact design due to high integration
- Reliable FM reception in noisy environments
- Simplified design with minimal external components
- Accurate signal strength measurement with RSSI output
Technical Details:
The MC13055DR2 operates on a supply voltage between 2.0V and 5.5V. The RSSI output provides an indication of the received signal strength, allowing for adaptive threshold adjustment and signal quality monitoring. The integrated local oscillator minimizes the need for external components, reducing the overall system cost and complexity. The data slicer converts the received FM signal into a digital data stream. The device is designed to operate in harsh environmental conditions, making it suitable for automotive and industrial applications. The small package size allows for easy integration into space-constrained designs.
