MC33594FTAER2 RF Receivers

The MC33594FTAER2 is an RF receiver that is specifically designed for use in modern telecommunications systems. It offers an integrated frequency synthesizer, a low power consumption, and an excellent sensitivity. The MC33594FTAER2 is a solution for applications requiring narrow band operation, such as digital cellular and telecommunications systems.

Application Field

The MC33594FTAER2 is suitable for applications in digital cellular and telecommunications systems, especially when used in the digital radio systems of GSM and CDMA. The MC33594FTAER2 is also applicable to ISM applications in the 433.9 to 914.9 MHz range which are mainly used for consumer applications such as security systems, toy communication, and remote controls. The device also supports variable bandwidths between 400 kHz and 2 MHz.

Working Principle

The MC33594FTAER2 is based on a switched capacitor filter which delivers low-IF signals suitable for digital demodulation. The filter is implemented in the input stage and allows an application-specific bandwidth choice. The low-IF signal is then converted to a digital signal, providing further information on the frequency, phase, and amplitude of the incoming signal.The MC33594FTAER2 provides two interrupt inputs, which allow the device to be triggered by external events. An embedded FM demodulator constantly facilitates digital demodulation for both FSK and MSK signals. Onboard calibration and adjustment features also allow fast, fault-tolerant tuning of the component.The device is capable of operating at low power while still maintaining its sensitivity. The MC33594FTAER2 works by drawing an average power of 75 mW and a peak power of 150mW. Additionally, a low-power standby modulation is available, which reduces the supply current to about 21 mA.The MC33594FTAER2 is also equipped with an integrated frequency synthesizer, allowing for easy tuning of the component. MC33594FTAER2 features a fast synthesizer settling time of 2.5 ms, and includes on-board calibration reference oscillators and adjustable slew rate option. This provides a stable and efficient tuning experience.To conclude, the MC33594FTAER2 is an integrable RF receiver specifically designed for digital cellular and telecommunications systems. It offers an integrated frequency synthesizer, low power consumption, excellent sensitivity, and variable bandwidths between 400 kHz and 2 MHz. Its on-board calibration features further make the MC33594FTAER2 a reliable receiver for a number of applications.
