The MAX41473/MAX41474 are high-performance, low-power receivers ideal for amplitude shift-keyed (ASK) and frequency shift-keyed (FSK) data. The receivers can be configured for three popular sub-1GHz bands while using a single low-cost 16MHz crystal: 287MHz to 320MHz, 425MHz to 480MHz, and 860MHz to 960MHz.

The MAX41473/MAX41474 are capable of ASK or FSK reception, and are also fully programmable through the I2C interface. In addition to the programmable option, the MAX41473/MAX41474 provide a preset option where no programming is required for defined configurations. The design allows for single wire operation to an external microcontroller.

The receiver has excellent RF sensitivity and allows input signals up to 0dBm of power at the RF input. With an integrated IF filter, a few external components, and low operating/power-down currents, the MAX41473/MAX41474 receivers are ideal for cost- and power-sensitive applications. The chips also include a low-noise amplifier (LNA), fully differential image-rejection mixer, on-chip phase-locked loop (PLL) with integrated voltage-controlled oscillator (VCO), received signal strength indicator (RSSI), and digital demodulation.

The devices operate in the 1.8V to 3.6V supply voltage range and also feature a power-saving, fully programmable, self-polling (duty cycling) mode with preamble detection and interrupt output to wake up an external microcontroller unit (MCU).

The parts are available in a 12-pin thin QFN (TQFN) package and are specified for the -40°C to +105°C extended temperature range.

Applications

  • Building Access Control
  • Garage Door Openers (GDO)
  • Home Automation and Security
  • Remote Keyless Entry (RKE)
  • Restaurant Pagers
  • Tire Pressure Monitoring Systems (TPMS)

Product Detail

The MAX4147X evaluation kit (EV kit) contains a single MAX4147X high output power VHF/UHF sub-GHz ISM/ SRD receiver designed to receive frequency-shift keying (FSK), Gaussian GFSK, or amplitude-shift keying (ASK) data in the 287MHz to 320MHz, 425MHz to 480MHz, and 860MHz to 960MHz frequency ranges.

The MAX41470, MAX41473, and MAX41474 EV kits operate in conjunction with an external microcontroller (MCU) and graphical user interface (GUI) software running on a computer. The MAX41470 uses an SPI interface for internal register configurations while the MAX41473/74 can use the preset modes or an I2C interface for register programming and control.

The MAX41473 and MAX41474 EV kits are also designed to operate with a simple, one-pin data interface, alleviating the need to program the part for nominal operation, or other high-level system (PC with GUI software) having to configure the receiver for operation. These parts allow the user to preset the operating frequencies by part selection and pin configurations. On the EV kit, selecting the frequency of operation is as simple as setting jumpers.

The EV kit includes Windows® 10-compatible software that provides a simple GUI for configuration of all the MAX4147X registers through the SPI or I2C ports. The GUI also controls the on-board PMIC when the MAX32630FTHR applications platform is used.

Applications

  • Building Access Control
  • Garage Door Openers (GDO)
  • Home Automation and Security
  • Remote Keyless Entry (RKE)
  • Restaurant Pagers
  • Tire Pressure Monitoring Systems (TPMS)
