General Description
The IC is a very low power consump- ^Package
tion single chip ASK Single Conver-
sion Receiver for receive frequencies
between 385 and 406MHz. The
Receiver offers a high level of integra-
tion and needs only a few external
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 data filter, a data comparator
(slicer) and a peak detector. Addition-
ally there is a power down feature to
save battery life.
