Description

Description:
The TDA 711x(F) products are single chip ASK/FSK transmitter operating in the 434 and 868MHz frequency band. The ICs offer a high level of integration and need only a few external components to build a complete transmitter solution. The products vary in package and supported frequency band.
The devices contain a fully integrated PLL synthesizer and a high efficiency power amplifier to drive the antenna. A special circuit design, a unique power amplifier and a power down feature contribute to low current consumption and to extended battery life. The ICs have a clock output for the micro-controller and as such enable the usage of only one crystal in the application. Additionally, TDA 7110 features a selectable clock divider ratio.
Summary of Features:
ASK and FSK modulation
Frequency range @ 25°C (depending on device):427 to 442MHz, 854 to 884MHz
High efficiency power amplifier (typ. +10dBm output power at 3V supply voltage)
Low supply current (depending on device): I s = ~14.0mA typ. in transmit mode (V s = 3V)
Very low supply current in power down mode (0.25nA typ.)
Supply voltage range 2.1 to 4V
Temperature range -40 to +85°C
Built-in low/high frequency switch for FSK Mode
Clock output for μC
TDA 7110 only:selectable clock divider ratio
Crystal oscillator in 13.5MHz band and 6MHz band (TDA 7110 only)
Fully integrated PLL frequency synthesizer
Fully integrated VCO (no need for external components)
Low external component count
