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.

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
