ATA2745

UHF ASK Transmitter

Atmel Corporation 

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-effectiveness

• One-chip Solution With Minimum External Circuitry

• Single-ended Open-collector Output (Same Antennas Can Be Used as in Discrete

Solutions, Simpler Matching of Magnetic Loop Antennas)

• ESD Protection According to MIL-STD 883 (4 KV HBM) Except Pins XTO1, XTO2, ANT

and LF

• Very Small SSO16 Package, Pitch 0.635, 150 mil

1. 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 sys-

tems. The main applications of the ATA2745 are in the areas of outside temperature

metering, socket control, garage door openers, consumption metering, light/fan or air-

conditioning controls, jalousies, wireless keyboards, and various other consumer

market applications.
