General Description
The IC is a very low power consump- Package
tion single chip FSK/ASK Superhet-
erodyne Receiver (SHR) for the re-
ceive frequency range between 902
and 928 MHz that is pin compatible to
the ASK Receiver TDA5202. The IC
offers a high level of integration and
needs only a few external compo-
nents. The device contains a low noise
amplifier (LNA), a double balanced
mixer, a fully integrated VCO, a PLL
synthesiser, a crystal oscillator, a lim-
iter with RSSI generator, a PLL FSK
demodulator, a data filter, a data com-
parator (slicer) and a peak detector.
Additionally there is a power down fea-
ture to save battery life.
Features
■ Low supply current (Is = 5.4 mA typ.
in FSK mode, Is = 4.8 mA typ. in
ASK mode)
■ Supply voltage range 5 V ±10%
■ Receive frequency range 902 to
928 MHz
■ Limiter with RSSI generation,
operating at 10.7 MHz
■ Power down mode with very low
supply current (90 nA typ.)
■ FSK and ASK demodulation capa-
bility
■ Fully integrated VCO and PLL
Synthesiser
■ ASK sensitivity better than
-109 dBm over specified tempera-
ture range (- 40 to +85°C)
■ Selectable reference frequency
■ 2nd order low pass data filter with
external capacitors
■ Data slicer with self-adjusting
threshold
■ FSK sensitivity better than
-102 dBm over specified tempera-
ture range (- 40 to +85°C)
Application ■ Keyless Entry Systems
■ Remote Control Systems
■ Low Bitrate ISM-band Communica-
tion Systems
