MAX7033 315MHz/433MHz ASK Superheterodyne Receiver with AGC Lock General Description Features The MAX7033 fully integrated low-power CMOS super- Optimized for 315MHz or 433MHz Band heterodyne receiver is ideal for receiving amplitude shift- Operates from Single +3.3V or +5.0V Supplies keyed (ASK) data in the 300MHz to 450MHz frequency High Dynamic Range with On-Chip AGC range. The receiver has an RF input signal range of AGC Hold Circuit -114dBm to 0dBm. With few external components and a 1ms AGC Release Time low-current power-down mode, it is ideal for cost-sensitive Selectable Image-Rejection Center Frequency and power-sensitive applications typical in consumer markets. The MAX7033 consists of a low-noise ampli- Selectable x64 or x32 f /f Ratio XTAL LO fier (LNA), a fully differential image-rejection mixer, an Low 5.2mA Operating Supply Current on-chip phase-locked loop (PLL) with integrated voltage- < 3.5A Low-Current Power-Down Mode for Efficient controlled oscillator (VCO), a 10.7MHz IF limiting amplifier Power Cycling stage with received-signal-strength indicator (RSSI), and 250s Startup Time analog baseband data-recovery circuitry. The MAX7033 Built-In 44dB RF Image Rejection also has a discrete one-step automatic gain control Better than -114dBm Receive Sensitivity (AGC) that reduces the LNA gain by 35dB when the RF input signal exceeds -62dBm. The AGC circuitry offers an -40C to +105C Operation externally controlled hold feature. Ordering Information The MAX7033 is available in 28-pin TSSOP and 32-pin TQFN packages and is specified over the extended PART TEMP RANGE PIN-PACKAGE (-40C to +105C) temperature range.
