Technical Description for 434MHz Receiver, Model: Elitescreen 434 MHz RF signal emitted from the transmitter (Model: Cinetension) sold with this product was received by the antenna and past to the LNA of HC01, FSK receiver, which consists of a fully integrated multi-band PLL synthesizer, an LNA with switchable gain, I/Q down converter mixers, baseband filters and amplifiers, and an I/Q demodulator followed by a data filter. HC01 demodulated the signal and past to U2 (EM78P260) via the connector SDI, SDO, SCK, NSEL. The demodulated data was decoded by U2 and communicated with U6 (AT24C02), and then fed back to U2, which control the motor to up or stop or down screen. The specification of HC01 Universal ISM Band FSK Receiver was attached with filename hc01.pdf.

HC01 Universal ISM Band FSK Receiver DESCRIPTION: HC01 HC01 is a single chip, low power, multi-channel FSK receiver designed for use in applications requiring FCC or ETSI conformance for unlicensed use in the 315, 433, 868, and 915 MHz bands. Used in conjunction with HC's FSK transmitters, the HC01 is a flexible, low cost, and highly integrated solution that does not require production alignments. All required RF functions are integrated. Only an external crystal and bypass filtering are needed for operation. The HC01 has a completely integrated PLL for easy RF design, and its rapid settling time allows for fast frequency hopping, bypassing multi-path fading, and interference to achieve robust wireless links. The PLL’s high resolution allows the usage of multiple channels in any of the bands. The baseband bandwidth (BW) is programmable to accommodate various deviation, data rate, and crystal tolerance requirements. The receiver employs the Zero-IF approach with I/Q demodulation, therefore no external components (except crystal and decoupling) are needed in a typical application. The HC01 is a complete analog RX and baseband receiver including a multi-band PLL synthesizer with an LNA, I/Q down converter mixers, baseband filters and amplifiers, and I/Q demodulator. The chip dramatically reduces the load on the microcontroller with integrated digital data processing: data filtering, clock recovery, data pattern recognition and integrated FIFO. The automatic frequency control (AFC) feature allows using a low accuracy (low cost) crystal. To minimize the system cost, the chip can provide a clock signal for the microcontroller, avoiding the need for two crystals. For low power applications, the device supports low duty-cycle operation based on the internal wake-up timer.

It covers the unlicensed frequency bands at 315, 433, 868, and 915 MHz. The device facilitates compliance with FCC and ETSI requirements. The programmable PLL synthesizer determines the operating frequency, while preserving accuracy based on the on-chip crystal-controlled reference oscillator. The PLL’s high resolution allows for the use of multiple channels in any of the bands. The receiver employs the Zero-IF approach with I/Q demodulation, allowing the use of a minimal number of external components in a typical application. The HC01 consists of a fully integrated multi-band PLL synthesizer, an LNA with switchable gain, I/Q down converter mixers, baseband filters and amplifiers, and an I/Q demodulator followed by a data filter. The HC VCO in the PLL performs automatic calibration, which requires only a few microseconds. Calibration always occurs when the synthesizer begins. If temperature or supply voltage changes significantly, VCO recalibration can be invoked easily. Recalibration can be initiated at any time by switching the synthesizer off and back on again. LNA The LNA has 250 Ohm input impedance, which works well with the recommended antennas. If the RF input of the chip is connected to 50 Ohm devices, an external matching circuit is required to provide the correct matching and to minimize the noise figure of the receiver. The LNA gain (and linearity) can be selected (0, –6, –14, –20 dB relative to the highest gain) according to RF signal strength. This is useful in an environment with strong interferers. Baseband Filters The receiver bandwidth is selectable by programming the bandwidth (BW) of the baseband filters. This allows setting up the receiver according to the characteristics of the signal to be received. An appropriate bandwidth can be selected to accommodate various FSK deviation, data rate, and crystal tolerance requirements. The filter structure is a 7-th order Butterworth low-pass with 40 dB suppression at 2*BW frequency. Offset cancellation is accomplished by using a high-pass filter with a cut-off frequency below 7 kHz. HC01 Data Filtering and Clock Recovery The output data filtering can be completed by an external capacitor or by using digital filtering according to the final application. Analog operation: The filter is an RC type low-pass filter and a Schmitt-trigger (St). The resistor (10k) and the St is integrated on the chip. An (external) capacitor can be chosen according to the actual bit-rate. In this mode the receiver can handle up to 256 kbps data rate. Digital operation: The data filter is a digital realization of an analog RC filter followed by a comparator with hysteresis. In this mode there is a clock recovery circuit (CR), which can provide synchronized clock to the data. With this clock the received data can fill the RX Data FIFO. The CR has three operation modes: fast, slow, and automatic. In slow mode, its noise immunity is very high, but it has slower settling time and requires more accurate data timing than …
