6 / 29 page Product Description 2 - 2 TDA 5100A preliminary Wireless Components Specification, March 2001 2.1 Overview The TDA 5100A is a single chip ASK transmitter for the frequency band 433- 435 MHz. 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 an unique power amplifier design are used to save current consumption and therefore to save battery life. Additional features like a power down mode, a low power detect and a divided clock output are implemented. 2.2 Applications Keyless entry systems Remote control systems Alarm systems Communication systems 2.3 Features fully integrated frequency synthesizer VCO without external components high efficiency power amplifier frequency range 433-435 MHz ASK modulation low supply current (typically 7 mA) voltage supply range 2.1 - 4 V power down mode low voltage sensor clock output for µC low external component count |
