The MAX1470EUI+ is a 315MHz low power, +3V super heterodyne receiver in 28 pin TSSOP package. It is a fully integrated low power CMOS superheterodyne receiver for use with amplitude-shift keyed (ASK) data in the 315MHz band. With few required external components and a low-current power-down mode, it is ideal for cost and power sensitive applications in the consumer markets. The chip consists of a 315MHz low-noise amplifier (LNA), an image rejection mixer, a fully integrated 315MHz phase-lock-loop (PLL), a 10.7MHz IF limiting amplifier stage with received-signal strength indicator (RSSI) and an ASK demodulator and analogue base band data-recovery circuitry.
