XHR2961 is a special integrated circuit for superheterodyne reception. It is a single-chip solution for ASK/OOK (ON-OFF Keyed) wireless reception.
This chip implements data input and data output, and internally integrates a low-noise amplifier, mixer, frequency synthesizer PLL, and
frequency amplifier, band-pass filter, peak detection circuit, and low-pass filter and comparator. The application circuit of this chip is simple and requires only a few
The component can realize the wireless signal receiving function.
The chip demodulates the received RF signal and outputs a CMOS level data signal to achieve "data in, data out". The working voltage of the chip is 2.8~5.5V, the current consumption is 5.2mA (433.92MHz) at 5V, and the typical sensitivity can reach up to -115dBm. The maximum data rate is 10Kbit/s and the operating temperature range is -30℃ to +85℃. Product advantages: Output CMOS signal, no noise. There are also 5 IOs available for use, including two high-current IOs with a drive capacity of up to 250mA and 3 PWM.

This chip solution is mainly suitable for systems that require simple structure and small scale in the industrial and consumer fields.
