Description and Introduction

UNIVERSAL NARROWBAND FM RECEIVER INTEGRATED CIRCUIT The MC13111BFB is a component manufactured by Motorola. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Motorola  
- **Part Number:** MC13111BFB  
- **Type:** RF/IF Demodulator  
- **Package:** SOP (Small Outline Package)  

### **Descriptions:**  
- The MC13111BFB is a monolithic FM IF system designed for low-power communication applications.  
- It integrates a limiter amplifier, quadrature detector, and logarithmic received signal strength indicator (RSSI).  
- Suitable for narrowband FM demodulation in RF applications.  

### **Features:**  
- **Frequency Range:** Operates at typical IF frequencies (e.g., 455 kHz, 10.7 MHz).  
- **Low Power Consumption:** Designed for battery-operated devices.  
- **High Sensitivity:** Includes a high-gain limiter amplifier for improved signal detection.  
- **RSSI Output:** Provides a logarithmic signal strength output for monitoring.  
- **Quadrature Detector:** Enables precise FM demodulation.  

This information is based solely on the available knowledge base for the MC13111BFB by Motorola.

Application Scenarios & Design Considerations

UNIVERSAL NARROWBAND FM RECEIVER INTEGRATED CIRCUIT

Alternative Part Number

  • MC13110AFB --: Same MC131xx series FM/IF subsystem in the same 44-pin QFP package, with closely matching function and pinout, making it a strong drop-in candidate.
  • MC13135FB --: Related Motorola FM receiver IC in the same package family, offering comparable IF/demodulator functionality for similar applications.
  • TDA7000 --: Widely available single-chip FM receiver IC that can serve as a functional substitute in FM radio designs, though pinout and external circuitry differ.
  • TDA7088T --: FM receiver IC with similar signal processing chain and low-voltage operation, suitable as a functional substitute in FM radio designs.
  • CXA1191M --: Integrated FM/AM radio receiver IC offering comparable receiver functionality and commonly used as an alternative in portable radio applications.
