General Description

The TDK 5111 is a single chip ASK/ Package

FSK transmitter for the frequency band

314-317 MHz. The IC offers a high

level of integration and needs only a

few external components. The device

contains a fully integrated PLL synthe-

sizer and a high efficiency power ampli-

fier to drive a loop antenna. A special

circuit design and an unique power

amplifier design are used to save cur-

rent consumption and therefore to save

battery life. Additionally features like a

power down mode, a low power detect

and a divided clock output are imple-

mented. The IC can be used for both

ASK and FSK modulation.
