The two LO signals are derived from an on-chip integer-N PLL frequency synthesizer. The PLL reference frequency is derived from a crystal (XTAL). As the first intermediate frequency (IF1) is very high, a reasonably high degree of image rejection is provided even without using an RF front-end filter. At applications asking for very high image rejections, cost-efficient RF front-end filtering can be realized by using a SAW filter in front of the LNA. The second mixer MIX2 is an image-reject mixer. The receiver signal chain is setup by one (or two) low noise amplifier(s) (LNA1, LNA2), two down-conversion mixers (MIX1, MIX2), an on-chip IF filter (IFF) as well as an IF amplifier (IFA). By choosing the required modulation via an FSK/ASK switch (at pin MODSEL), either the on-chip FSK demodulator (FSK DEMOD) or the RSSI-based ASK detector is selected. A second order data filter (OA1) and a data slicer (OA2) follow the demodulator. The data slicer threshold can be generated from the mean-value of the data stream or by means of the positive and negative peak detectors (PKDET+/-). A digital post-processing of the sliced data signal can be performed by a noise filter (NF) building block. The dual LNA configuration can be used for antenna space diversity or antenna frequency diversity or to setup an LNA cascade (to further improve the input sensitivity). The two LNAs can also be setup to feed the RF signal differentially. A sequencer circuit (SEQ) controls the timing during start-up. This is to reduce start-up time and to minimize power dissipation. A clock output, which is a divide-by-8 version of the crystal oscillator signal, can be used to drive a microcontroller. The clock output is open collector and gets activated through a load connected to positive supply. 1.2 Technical Data Overview Input frequency ranges: 300 to 470MHz 610 to 930MHz Power supply range: 2.1 to 5.5V Temperature range: -40 to +125°C Shutdown current: 50 nA Operating current: 10.0 to 11.1mA Internal IF: 1.8MHz with 300kHz 3dB bandwidth FM/FSK deviation range: ±10kHz to ±100kHz Image rejection: 65dB 1st IF (with external RF front-end filter) 25dB 2nd IF (internal image rejection) Maximum data rate: 50kps RZ (bi-phase) code, 100kps NRZ Spurious emission: < -54dBm Linear RSSI range: > 60dB Crystal reference frequency: 16 to 27MHz MCU clock frequency: 2.0 to 3.4MHz Input Sensitivity: at 4kbps NRZ, BER = 3·10-3 Frequency 315 MHz 433 MHz 868 MHz 915 MHz FSK internal IF2=1.8MHz, 300kHz BW, Δf = ±20kHz -107dBm -107dBm -104dBm -102dBm ASK internal IF2=1.8MHz, 300kHz BW -112dBm -112dBm -108dBm -105dBm Note: - Sensitivities given for RF input 1 (without SAW filter) - Sensitivity for RF input 2 is about 2 to 3dB worse (because of SAW filter loss) 39012 71121 01 Rev. 004 Page 3 of 18 EVB Description Mar/09 EVB71121 300 to 930MHz Receiver Evaluation Board Description 24 14 2 LNA1 FSK MIX1 IFF MIX2 IFA OA1 FSK DEMOD SEQ BIAS 30 LF PKDET_ PDN 21 OA2 DIV 8 CP 25 Fig. 1: 20 PDP SW2 RO ENRX 26 18 PFD VCO 31 TEST N2 counter 28 15 SLCSEL RFSEL N1 counter CLKO 7 PKDET+ 100k LNA2 VEE ROI 8 LO2 100k 32 LO1 DFO SW1 100k LNASEL LNAI2 100k NCF DTAO 29 CINT 22 19 SLC 1 100k 16 ASK VCC LNAI1 17 DF2 27 DF1 13 RSSI 12 IFSEL 11 VEE 10 MIXO 9 VCC 5 MIXN 4 MODSEL VEE 6 MIXP 3 LNAO2 Block Diagram LNAO1 1.3 23 MLX71121 block diagram The MLX71121 receiver IC consists of the following building blocks: • • • • • • • • • • • • • PLL synthesizer (PLL SYNTH) to generate the first and second local oscillator signals LO1 and LO2.

Fig. 2 shows this for the case of receiving at fRF(high-high). In the example of Fig. 2, the image signals at fRF(lowhigh) and fRF(low-low) are suppressed by the bandpass characteristic provided by the RF front-end. The bandpass shape can be achieved either with a SAW filter (featuring just a couple of MHz bandwidth), or by the tank circuits at the LNA input and output (this typically yields 30 to 60MHz bandwidth). In any case, the high value of the first IF (IF1) helps to suppress the image signals at fRF(low-high) and fRF(low-low). The two remaining signals at IF1 resulting from fRF(high-high) and fRF(high-low) are entering the second mixer MIX2. This mixer features image rejection with so-called single-sideband (SSB) selection. This means either the upper or lower sideband of IF1 can be selected. In the example of Fig. 2, LO2 high-side injection has been chosen to select the IF2 signal resulting from fRF(high-high). f LO2 f RF Fig. 2: f RF f LO2 f LO1 f RF f RF The four receiving frequencies in a double conversion superhet receiver It can be seen from the block diagram of Fig. 1 that there is a fixed relationship between the LO signal frequencies (fLO1 , fLO2) and the reference oscillator frequency fRO. f LO1 = N 1 ⋅ f LO2 f LO2 = N 2 ⋅ f RO The operating frequency of the internal IF filter (IFF) and FSK demodulator (FSK DEMOD) is 1.8MHz. Therefore the second IF (IF2) is set to 1.8MHz as well. 39012 71121 01 Rev. 004 Page 6 of 18 EVB Description Mar/09 EVB71121 300 to 930MHz Receiver Evaluation Board Description 2.1 Calculation of Frequency Settings The receiver has two predefined receive frequency plans which can be selected by the RFSEL control pin.
