TDA 5100
Product Brief
TDA 5100
ASK/FSK Transmitter
Potential Application
Keyless entry systems
Remote control systems
Alarm systems
Communication systems
Features
Low supply current
Supply voltage range 2.1-4 V
Power down mod e
Fully integrated VCO, PLL and
power amplifier
Switchable frequency range
868-870 / 433-435 MHz
Selectable crystal oscillator
6.78 / 13.56 MHz
Programmable divided clock
output for µC
Low external component count
ASK/FSK modulation
The IC is a single chip ASK/FSK
transmitter for the frequency bands
868-870 MHz and 433-435 MHz.
The transmitter offers a high level
of integration and needs only a
few external components.
The device contains a fully
integrated VCO, a PLL synthesizer,
a crystal oscillator with a divided
clock output to drive a microcon-
troller and a power amplifier to
drive a loop antenna. Additionally
there is a power down feature to
save battery life and a low voltage
sensor which can be used to
disable the power amplifier. The
IC can be used for both ASK and
FSK modulation.
