TDA7110 Product Info Product Info The TDA7110 is a single chip ASK/FSK Package transmitter for the frequency bands 868-870 MHz and 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. Additionally features like a power down mode, a low power detect, a selectable crystal oscillator frequency and a divided clock output are implemented. The IC can be used for both ASK and FSK modulation. • fully integrated frequency synthe- • voltage supply range - 4 V sizer • power down mode • VCO without external components • low voltage sensor • high efficiency power amplifier typically 10 dBm 3 V • selectable crystal oscillator MHz/13.56 MHz • switchable frequency range 868-870/433-435 MHz • programmable divided clock output for µC • ASK/FSK modulation • low external component count • low supply current typ. 13 Applications • Keyless entry systems • Remote control systems • Alarm systems • Communication systems Ordering Information Type TDA7110 available on tape and reel Ordering Code SP000524278 Package PG-TSSOP-16 Wireless Components Product Info Data Sheet, December 2008 1 Product Description Contents of this Chapter Overview. 1-2 Applications 1-2 Features 1-2 Package Outlines 1-3 TDA7110 Product Description Overview The TDA7110 is a single chip ASK/FSK transmitter for the frequency bands 868-870 MHz and 433-435 MHz.
