Product Info
General Description
The TDK 5111 is a single chip ASK/
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.
