TDK5111F

概要

TDK5111F - Transmitter with power down mode and divided clock output

The TDK5111F is a single chip ASK/FSK transmitter for the frequency bands 311 to 317MHz. The IC offers a high level of integration and needs only a few external components. The device contains a fully integrated PLL synthesizer and a high efficiency power amplifier to drive a loop antenna. A special circuit design and a unique power amplifier design are used to save current consumption and therefore to save battery life. The IC can be used for both ASK and FSK modulation.
