For FM/FSK reception the IF tank used in the phase coincidence demodulator can be constituted either by a ceramic resonator or an LC tank (optionally with a varactor diode to create an AFC circuit). In ASK configuration, the RSSI signal is feed to an ASK detector, which is constituted by the operational amplifier. Demodulation Type of receiver FM / FSK narrow-band RX with ceramic demodulation tank FM / FSK wide-band RX with LC demodulation tank ASK RX with RSSI-based demodulation A double-conversion variant, called TH71112, is also available. This receiver IC allows a higher degree of image rejection, achieved in conjunction with an RF frontend filter. Both RXICs have the same die. At the TH71112, the second mixer (MIX2) is used to down-convert the first IF (IF1) to the second IF (IF2). At the TH71111, MIX2 operates as an amplifier. Efficient RF frontend filtering is realized by using a SAW, ceramic or helix filter in front of the LNA and by adding an LC filter at the LNA output. 390127111101 Rev. 004 2 of 16 EVB Description Aug/02 EVB71111 868/915MHz Receiver Evaluation Board Description 18 OUT_OA 19 20 OA OAN OAP 24 23 OUTN OUTP Block Diagram 17 VCC_BIAS BIAS ENRX 28 16 MIX3 IN_DEM 22 VEE_BIAS 15 OUT_IFA 27 14 VCC_PLL VEE_RO 26 13 FPC2 RO RO IFA 21 25 RSSI 12 FBC1 11 PFD IN_IFA 8 MIX2 29 VCC_MIX DIV_32 9 CP IF OUT_MIX2 LF 10 VEE_IF IF 7 IF1N VCO1 MIX1 5 VEE_MIX LO 6 IF1P 4 IN_MIX1 VEE_LNA GAIN_LNA VCC_LNA 32 LNA 31 1 VEE_LNAC IN_LNA 2 30 3 OUT_LNA Fig. 1: TH71111 block diagram 390127111101 Rev. 004 3 of 16 EVB Description Aug/02 EVB71111 868/915MHz Receiver Evaluation Board Description Frequency Planning Frequency planning is straightforward for single-conversion applications because there is only one IF that might be chosen, and then the only possible choice is low-side or high-side injection of the LO signal (which is now the one and only LO signal in the receiver). The receiver’s single-conversion architecture requires careful frequency planning. Besides the desired RF input signal, there are a number of spurious signals that may cause an undesired response at the output. Among them is the image of the RF signal that must be suppressed by the RF front-end filter. By using the internal PLL synthesizer of the TH71111 with the fixed feedback divider ratio of N = 32 (DIV_32), two types of down-conversion are possible: low-side injection of LO and high-side injection of LO. The following table summarizes some equations that are useful to calculate the crystal reference frequency (REF), the IF and the LO frequency respectively, for a given RF. Injection type low high REF (RF – IF)/32 (RF + IF)/32 LO 32•REF 32•REF IF RF – LO LO – RF RF image RF – 2IF RF + 2IF The following table depicts crystal, LO and image signals considering the examples of 868.3 MHz and 915 MHz RF reception at IF = 10.7 MHz. Signal type RF = 868 MHz RF = 868 MHz RF = 915 MHz RF = 915 MHz Injection type Low high low high 26.80000 27.46875 28.25938 28.92813 LO / MHz 857.6 879.0 904.3 925.7 RF image/MHz 879.0 857.6 925.7 904.3 RF image/MHz 846.9 889.7 893.6 936.4 REF / MHz The selection of the reference crystal frequency is based on some assumptions. As for example: the image frequency should not be in a radio band where strong interfering signals might occur (because they could represent parasitic receiving signals), the LO signal should be in the range of 800 MHz to 915 MHz (because this is the optimum frequency range of the VCO1). Furthermore the IF should be as high as possible to achieve highest RF image rejection. The columns in bold depict the selected frequency plans to receive at 866.3 MHz and 915 MHz, respectively.
