ATA2745 - UHF ASK Transmitter

Description

The ATA2745 is a PLL transmitter IC which has been developed especially for the demands of RF low-cost data transmission systems at data rates up to 20 kBaud.

The transmitting frequency range is 310 MHz to 440 MHz.

It can be used in ASK systems.

Features

  • Very High Transmitting Frequency Accuracy Compared to SAW Solutions.
  • (Enables Receivers at Lower Bandwidth than With SAW Resonators) Lower Cost than the Usual Discrete Solutions Using SAW and Transistors Supply Voltage 2.2V to 4.0V in the Temperature Range of.
  • 40°C to 85°C XTO Output for Clocking the Microcontroller, Thereby, Together with the ATAR090 or ATAR890, Resulting in the Optimum System Cost-effectiven.
