Description
The RX3400 is a low power ASK receiver IC which is fully compatible with the Mitel
KESRX01 IC and is suitable for use in a variety of low power radio applications including
remote keyless entry. The RX3400 is based on a single-conversion, super-heterodyne
receiver architecture and incorporates an entire phase-locked loop (PLL) for precise local
oscillator generation. In addition, the RX3400 provides an RSSI output.
