General Description
The IC is a low power consumption single chip FSK/ASK
Transceiver for half duplex low datarate communication in the
315MHz band. The IC offers a very high level of integration and
needs only a few external components. It contains a highly
efficient power amplifier, a low noise amplifier (LNA) with AGC,
a double balanced mixer, a complex direct conversion stage, I/
Q limiters with RSSI generation, an FSK demodulator, a fully
integrated VCO and PLL synthesizer, a tuneable crystal
oscillator, an onboard data filter, a data comparator (slicer),
positive and negative peak detectors, a data rate detection
circuit and a 2/3-wire bus interface. Additionally there is a power
down feature to save battery power.
Features
– Low supply current (I
s
= 9mA typ. receive, I
s
= 13mA typ. transmit mode)
– Supply voltage range 2.1 - 5.5V
– Power down mode with very low supply
current consumption
– FSK and ASK modulation and demodulation
capability
– Fully integrated VCO and PLL
synthesizer and loop filter on-chip with on
chip crystal oscillator tuning
– I
2
C/3-wire μController Interface
– On-chip low pass channel select filter and
data filter with tuneable bandwidth
– Data slicer with self-adjusting threshold and
2 peak detectors
– FSK sensitivity <-109dBm, ASK sensitivity <
–109dBm
