Description

The U2745B 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 310 MHz to 440 MHz. It can be used in ASK sys-

tems. The main applications of the U2745B are in the areas of outside temperature

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

condition control, jalousies, wireless keyboard and various other consumer market

applications.
