The MAX7042ATJ+ is a fully integrated, low-power, CMOS superheterodyne RF receiver designed for frequency-shift-keyed (FSK) data reception. It supports data rates up to 66kbps NRZ and requires minimal external components for operation.
This receiver is capable of operating at user-selectable carrier frequencies including 308, 315, 418, and 433.92MHz. It boasts impressive RF input sensitivity, reaching -110dBm at 315MHz and -109dBm at 433.92MHz. The device integrates essential components such as a low-noise amplifier (LNA), an image-rejection mixer, a phase-locked loop (PLL), and a local oscillator (LO).
Key features include a fast startup time of less than 250µs and low operating supply current. The MAX7042ATJ+ is specified for an automotive temperature range of -40°C to +125°C. It is supplied in a compact 32-pin TQFN package suitable for surface mounting.
Applications for the MAX7042ATJ+ include remote keyless entry (RKE), tire-pressure monitoring (TPM), home and office lighting control, remote sensing, smoke alarms, home automation, local telemetry systems, and security systems.
