6 / 35 page Product Description 2 - 2 TDA 5102 Wireless Components Specification, October 2001 2.1 Overview The TDA 5102 is a single chip ASK/FSK transmitter for the frequency band 905- 925 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, a selectable crystal oscillator frequency and a divided clock out- put are implemented. The IC can be used for both ASK and FSK modulation. 2.2 Applications I Keyless entry systems I Remote control systems I Alarm systems I Communication systems 2.3 Features I fully integrated frequency synthesizer I VCO without external components I high efficiency power amplifier I frequency range 905-925 MHz I ASK/FSK modulation I low supply current (typically 7 mA) I voltage supply range 2.1 - 4 V I power down mode I low voltage sensor I selectable crystal oscillator 7.15 MHz/14.3 MHz I programmable divided clock output for µC I low external component count |
