MAX41473/MAX41474

290MHz to 960MHz ASK/FSK Receiver

with I C Interface

General Description

Benefits and Features

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.

● Low Bill of Materials (BOM)

• No External Balun, No External Filter, etc.

• Single Low-Cost 16MHz External Crystal

● Long Range with High Sensitivity

● Low Power Consumption

• 9mA Operating Supply Current

• 10nA Power-Down Current

The MAX41473/MAX41474 are capable of ASK or FSK

reception, and are also fully programmable through the

● Self-Polling (Remote Wake-Up) for Reduced Power

• Preamble Detection with Interrupt Output

• Average Current as Low as 350μA

• Duty Cycle Less Than 1% Capable

• Fast Startup Time

I C 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 mi-

crocontroller.

● Automatic Gain Control (AGC) Adjusted Digital RSSI

● Automatic Frequency Control (AFC)

● Fast Frequency Switching Frac-N Synthesizer

● 33dB Calibrated Image Rejection

● Passes ETSI Category 2 Blocking Requirements

● ±2.5kV HBM ESD Protection, ±4kV on LNA Input

● Up to 200kbps Data Rate (NRZ)

● 1.8V to 3.6V Supply Voltage

● -40°C to +105°C Operating Temperature Range

● 4mm x 4mm, 12-TQFN with 0.8mm Pitch

The receiver has excellent RF sensitivity and allows input

signals up to 0dBm of power at the RF input. With an in-

tegrated IF filter, a few external components, and low op-

erating/power-down currents, the MAX41473/MAX41474

receivers are ideal for cost- and power-sensitive applica-

tions. The chips also include a low-noise amplifier (LNA),

fully differential image-rejection mixer, on-chip phase-

locked loop (PLL) with integrated voltage-controlled oscil-

lator (VCO), received signal strength indicator (RSSI), and

digital demodulation.

Ordering Information appears at end of data sheet.

The devices operate in the 1.8V to 3.6V supply voltage

range and also feature a power-saving, fully programma-

ble, self-polling (duty cycling) mode with preamble detec-

tion and interrupt output to wake up an external microcon-

troller unit (MCU).

The parts are available in a 12-pin thin QFN (TQFN) pack-

age and are specified for the -40°C to +105°C extended

temperature range.

Applications

● Home Automation and Security

● Building Access Control

● Garage Door Openers (GDO)

● Remote Keyless Entry (RKE)

● Tire Pressure Monitoring Systems (TPMS)

● Restaurant Pagers
