Description

The Atmel U2640B is a monolithic integrated circuit designed as a low-voltage FM receiver. It is tailored for use in various wireless communication applications, providing a compact and efficient solution for receiving FM signals. This IC is particularly well-suited for cordless applications.

Applications

  • Cordless Telephones
  • Wireless Headphones
  • Remote Control Systems
  • Pagers
  • FM Radio Receivers

Features

  • Low Supply Voltage: Operates at low voltages, making it suitable for battery-powered devices.
  • Low Current Consumption: Maximizes battery life in portable applications.
  • Integrated Mixer: Simplifies receiver design.
  • Integrated Local Oscillator: Reduces external component count.
  • RSSI Output: Provides signal strength indication.
  • FM Demodulation: Performs frequency demodulation to recover the audio signal.
  • Mute Function: Prevents unwanted noise during weak signal conditions.

Benefits

  • Extended Battery Life: Low power consumption ensures prolonged operation in portable devices.
  • Reduced System Cost: Integrated functionality minimizes the need for external components, reducing overall system cost.
  • Simplified Design: High level of integration streamlines the design process.
  • Improved Signal Quality: Good sensitivity allows for reliable reception even with weak signals.
  • Compact Solution: Small package size enables compact designs.

Additional Details

The U2640B typically operates from a supply voltage range of 2.5V to 5V. It's designed for FM frequencies, typically around 400MHz to 950MHz. Consult the Atmel datasheet for precise specifications regarding sensitivity, image rejection, and audio output levels. The receiver includes automatic frequency control (AFC) to maintain accurate tuning. It is available in a small surface mount package.

Further technical details include the Intermediate Frequency (IF) used in the receiver architecture, the characteristics of the audio output amplifier, and the specifics of the RSSI output. Refer to the Atmel documentation for complete details on these and other parameters.
