MICRF220
300MHz to 450MHz, 3.3V ASK/OOK Receiver
with RSSI and Squelch
General Description
The MICRF220 is a 300MHz to 450MHz super-
heterodyne, image-reject, RF receiver with automatic
gain control, ASK/OOK demodulator, analog RSSI
output, and integrated squelch features. It only requires
a crystal and a minimum number of external components
to implement. The MICRF220 is ideal for low-cost, low-
power, RKE, TPMS, and remote actuation applications.
The MICRF220 achieves
−110dBm
sensitivity at a bit
rate of 1kbps with 0.1% BER. Four demodulator filter
bandwidths are selectable in binary steps from 1625Hz
to 13kHz at 433.92MHz, allowing the device to support
bit rates up to 20kbps. The device operates from a
supply voltage of 3.0V to 3.6V, and typically consumes
4.3mA of supply current at 315MHz and 6.0mA at
433.92MHz. A shutdown mode reduces supply current to
0.1μA typical. The squelch feature decreases the activity
on the data output pin until valid bits are detected while
maintaining overall receiver sensitivity.
