Product Overview

The MAX1473EUI+ is a 315MHz/433MHz ASK superheterodyne receiver with extended dynamic range in 28 pin TSSOP package. This fully integrated low power CMOS receiver is ideal for receiving amplitude shift-keyed (ASK) data in the 300MHz to 450MHz frequency range. Its signal range is from -114dBm to 0dBm. With few external components and a low current power down mode it is ideal for cost and power sensitive applications typical in automotive and consumer markets. The chip consists of a low noise amplifier LNA , a fully differential image rejection mixer, an on-chip phase locked loop with integrated voltage controlled oscillator, a 10.7MHz IF limiting amplifier stage with received signal strength indicator and analogue baseband data recovery circuitry. It also has a discrete one step automatic gain control that drops the LNA gain by 35dB when the RF input signal is greater than -57dBm. It is used in automotive remote keyless entry, garage door openers, remote controls & home automation.
  • Operates from single 3.3V or 5.0V supplies
  • Operating temperature range from -40°C to 85°C
  • Receiver input frequency range from 300MHz to 450MHz
  • High dynamic range with on-chip AGC, selectable image rejection centre frequency
  • Selectable x64 or x32 fLO/fXTAL ratio
  • Low 5.2mA operating supply current
  • Low current power down mode for efficient power cycling < 2.5µA
  • 250µs start-up time, built-in 50dB RF image rejection
  • Receive sensitivity of -114dBm
