Product Info
General Description
The IC is a very low power consump-
tion single chip FSK/ASK Superhet-
erodyne Receiver (SHR) for the
frequency band 310 to 350 MHz that is
pin compatible with the ASK Receiver
TDA5201. The IC offers a high level of
integration and needs only a few exter-
nal components. The device contains
a low noise amplifier (LNA), a double
balanced mixer, a fully integrated
VCO, a PLL synthesiser, a crystal
oscillator, a limiter with RSSI genera-
tor, a PLL FSK demodulator, a data fil-
ter, a data comparator (slicer) and a
peak detector. Additionally there is a
power down feature to save battery
life.
Features
