MAX7042規(guī)格書詳情
General Description
The MAX7042 fully integrated, low-power, CMOS superheterodyne RF receiver is designed to receive? frequency-shift-keyed (FSK) data at rates up to 66kbps nonreturn-to-zero (NRZ) (33kbps Manchester). The MAX7042 requires only a few external components to realize a complete wireless RF receiver at 308, 315, 418, and 433.92MHz.
The MAX7042 includes all the active components
required in a superheterodyne receiver including a low noise amplifier (LNA), an image-rejection (IR) mixer, a fully integrated phase-locked loop (PLL), local oscillator (LO), 10.7MHz IF limiting amplifier with received-signal-strength indicator (RSSI), low-noise FM demodulator, and a 3V regulator. Differential peak-detecting data demodulators are included for baseband data recovery.
The MAX7042 is available in a 32-pin TQFN and is specified over the automotive -40°C to +125°C temperature range.
