TDA 7210 - Infineon

Product Brief
TDA 7210
ASK/FSK Receiver for the 434 and 868 MHz Frequency Band
Main Features
The TDA 7210 IC is a single chip ASK/FSK Superheterodyne Receiver
(SHR) for the 434 and 868 MHz frequency band with very low power
consumption. It offers a high level of integration and only a few external
components are needed to build a fully functional superheterodyne receiver.
„„
„„
Frequency range:
400 to 440MHz, 810 to 870MHz
„„
The device contains a low noise amplifier (LNA), a double balanced mixer, a
fully integrated VCO, a PLL synthesizer, a crystal oscillator for the reference
frequency, a limiter with RSSI generator, a PLL-based FSK demodulator, a data
filter, a data comparator (slicer) and a peak detector.
ASK and FSK demodulation
ASK sensitivity typically -110dBm
over specified temperature range
(-40 to +85°C)
„„
FSK sensitivity typically -103dBm
over specified temperature range
(-40 to +85°C)
Additionally a power - down feature is available, which saves current and
extends the battery life.
