Description and Introduction

308MHz/315MHz/418MHz/433.92MHz Low-Power, FSK Superheterodyne Receiver The MAX7042ATJ+T is a high-performance, crystal-referenced phase-locked loop (PLL) transmitter manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Frequency Range:** 300MHz to 450MHz  
- **Modulation:** ASK/OOK (Amplitude Shift Keying/On-Off Keying)  
- **Supply Voltage:** 2.1V to 3.6V  
- **Output Power:** Adjustable up to +13dBm  
- **Current Consumption:**  
  - 11.8mA (typical) at +10dBm output  
  - 7.4µA (typical) in shutdown mode  
- **Data Rate:** Up to 100kbps  
- **Reference Oscillator:** Crystal-based (10MHz to 14MHz)  
- **Package:** 32-pin TQFN-EP (5mm x 5mm)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The MAX7042ATJ+T is designed for low-power wireless applications, providing reliable RF transmission with crystal-based frequency accuracy. It integrates a PLL, VCO, and power amplifier, supporting ASK/OOK modulation for simple data encoding.  

### **Features:**  
- **Low Power Consumption:** Optimized for battery-powered devices.  
- **Adjustable Output Power:** Configurable via external components.  
- **Crystal-Referenced PLL:** Ensures high frequency stability.  
- **Fast Startup Time:** <250µs from shutdown mode.  
- **Integrated Power Amplifier (PA):** Simplifies RF design.  
- **Shutdown Mode:** Reduces power consumption when idle.  
- **Small Form Factor:** Suitable for compact designs.  

This device is commonly used in remote keyless entry (RKE), tire pressure monitoring (TPMS), and other short-range wireless applications.  

(Note: Always refer to the official datasheet for detailed technical specifications and application guidelines.)
