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 2.0 V to 5.5 V in the Temperature Range -20 C to 70 C
Supply Voltage 2.2 V to 5.5 V in the Temperature Range -40 C to 85 C
XTO Output for Clocking the Microcontroller, Thereby Together with the ATAR090 or
ATAR890 Results in the Optimum System Cost-effectiveness
One-chip Solution with Minimum External Circuitry
Very Small SSO16 Package, Pitch 0.635, 150 mil
“Single-ended Open-collector” Output (Same Antennas as in Discrete Solutions Can
Be Used, Simpler Adaptation of Magnetic Loop Antennas)
Very Large FSK Frequency Deviation Achievable by ±100 ppm Pulling of the Reference
Crystal
Enables Receivers at Lower Bandwidth than with SAW Resonators
ESD Protection According to MIL-STD.883 (4 KV HBM) Except Pins XTO1/ 2,
ANT and LF
Electrostatic sensitive device.
Observe precautions for handling.
Description
The U2741B is a PLL transmitter IC which has been especially developed for the
demands of RF low-cost data transmission systems at data rates up to 20 kBaud.
The transmitting frequency range is 300 MHz to 450 MHz. The device can be used in
both FSK and ASK systems.
