MAX41470

290MHz to 960MHz ASK/FSK Receiver with SPI

Interface

General Description

Benefits and Features

The MAX41470 is a high-performance, low-power receiver

that is ideal for amplitude shift-keyed (ASK) and frequency

shift-keyed (FSK) data. The receiver 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 MAX41470 is capable of both ASK and FSK reception

and is also fully programmable through an SPI interface.

● 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

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 MAX41470 receiver

is ideal for cost- and power-sensitive applications. The

chip also includes a low-noise amplifier (LNA), fully dif-

ferential image-rejection mixer, on-chip phase-locked loop

(PLL) with integrated voltage-controlled oscillator (VCO),

received signal strength indicator (RSSI), and digital de-

modulation.

● 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 device operates in the 1.8V to 3.6V supply voltage

range and also features 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).

Ordering Information appears at end of datasheet.

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
