MICRF219A
300MHz to 450MHz ASK/OOK Receiver with
Auto-Poll, RSSI, and Squelch
General Description
Features
The MICRF219A 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 MICRF219A is ideal for low-cost, low-power, RKE,
TPMS, and remote actuation applications.
The MICRF219A 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 0.1 μ A typical.
The squelch feature decreases the activity on the data
output pin until valid bits are detected while maintaining
overall receiver sensitivity.
