Description and Introduction

FSK Demodulator/ Tone Decoder The XR-2211ACP is a precision phase-locked loop (PLL) IC manufactured by EXAR Corporation. Below are the factual details about the part:  

### **Specifications:**  
- **Manufacturer:** EXAR  
- **Type:** Phase-Locked Loop (PLL) IC  
- **Package:** 16-pin DIP (Dual In-line Package)  
- **Operating Voltage:** 4.5V to 20V  
- **Frequency Range:** 0.01Hz to 300kHz  
- **Operating Temperature Range:** 0°C to +70°C  
- **Low Power Consumption:** Typically 6mA at 5V  
- **High Stability:** Low drift with temperature and supply variations  

### **Descriptions:**  
- The XR-2211ACP is designed for frequency demodulation, frequency synthesis, and data synchronization applications.  
- It features a voltage-controlled oscillator (VCO), phase comparator, and loop amplifier in a single monolithic IC.  
- Suitable for FSK demodulation, tone decoding, and frequency multiplication/demodulation.  

### **Features:**  
- **Wide Operating Voltage Range:** 4.5V to 20V  
- **Adjustable VCO Frequency Range:** Set by external RC components  
- **High Input Sensitivity:** Compatible with low-level signals  
- **Low Harmonic Distortion:** Ensures clean signal processing  
- **Built-in Phase Comparator:** Enables precise phase locking  
- **Stable Operation:** Minimal drift with temperature and voltage changes  

This information is based on EXAR's official documentation for the XR-2211ACP.

Application Scenarios & Design Considerations

FSK Demodulator/ Tone Decoder

Alternative Part Number

  • LTC6992CS6 --: Precision voltage-controlled oscillator in SOT-23 package, functionally similar to the XR-2211 VCO-based tone decoder and widely available.
  • NE567N --: Classic tone decoder/PLL IC with similar frequency detection function, available in DIP-8, a common substitute for tone decoder applications.
  • LM567CN --: Widely used tone decoder IC with comparable detection and PLL functionality, DIP-8 package, easy drop-in for many XR-2211 designs.
