All information contained in this datasheet is subject to change without prior notice. HiMARK Technology, Inc. assumes no responsibility for the use of any circuits shown in this datasheet. 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.
