General Description
The MLX71120 is a multi-band, single-channel RF receiver based on a double-conversion super-heterodyne architecture. It can receive FSK and ASK modulated signals. The IC is designed for general purpose applications for example in the European bands at 433MHz and 868MHz or for similar applications in North America or Asia, e.g. at 315MHz or 915MHz. It is also well-suited for narrow-band applications according to the ARIB STD-T67 standard in the frequency range 426MHz to 470MHz. The receiver's extended temperature and supply voltage ranges make the device a perfect fit for automotive or similar applications where harsh environmental conditions are expected.

1.1
Theory of Operation
General
The MLX71120 receiver architecture is based on a double-conversion super-heterodyne approach. 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) and an external IF filter with an on-chip 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 drain and gets activated through a load connected to positive supply.

300 to 930MHz Receiver Evaluation Board Description 2 Frequency Planning
Because of the double conversion architecture that employs two mixers and two IF signals, there are four different combinations for injecting the LO1 and LO2 signals: LO1 high side and LO2 high side: LO1 high side and LO2 low side: LO1 low side and LO2 high side: LO1 low side and LO2 low side: receiving at fRF(high-high) receiving at fRF(high-low) receiving at fRF(low-high) receiving at fRF(low-low)
As a result, four different radio frequencies (RFs) could yield one and the same second IF (IF2). 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).

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 IF2 frequency can be selected to 455kHz or 10.7MHz via the logic level at the IFSEL control pin. At the same time the output impedance of the 2nd mixer at pin MIXO is set according to the IF2 (please refer to pin description for details). Of course, also the operating frequency of the FSK demodulator (FSK DEMOD) is set accordingly.

2.1 Calculation of Frequency Settings
The receiver has two predefined receive frequency plans which can be selected by the RFSEL control pin. Depending on the logic level of RFSEL pin the sideband selection of the second mixer and the counter settings for N1 and N2 are changed accordingly.

433/868MHz Frequency Diversity
The receiver's multi-band functionality can be used to operate at two different frequency bands just by changing the logic level at pin RFSEL and without changing the crystal.

300 to 930MHz Receiver Evaluation Board Description 6 Reliability Information
This Melexis device is classified and qualified regarding soldering technology, solderability and moisture sensitivity level, as defined in this specification, according to following test methods: Reflow Soldering SMD's (Surface Mount Devices) * * IPC/JEDEC J-STD-020 "Moisture/Reflow Sensitivity Classification for Nonhermetic Solid State Surface Mount Devices (classification reflow profiles according to table 5-2)" EIA/JEDEC JESD22-A113 "Preconditioning of Nonhermetic Surface Mount Devices Prior to Reliability Testing (reflow profiles according to table 2)"
Wave Soldering SMD's (Surface Mount Devices) and THD's (Through Hole Devices) * * EN60749-20 "Resistance of plastic- encapsulated SMD's to combined effect of moisture and soldering heat" EIA/JEDEC JESD22-B106 and EN60749-15 "Resistance to soldering temperature for through-hole mounted devices"
Iron Soldering THD's (Through Hole Devices) * EN60749-15 "Resistance to soldering temperature for through-hole mounted devices"
Solderability SMD's (Surface Mount Devices) and THD's (Through Hole Devices) * EIA/JEDEC JESD22-B102 and EN60749-21 "Solderability"
For all soldering technologies deviating from above mentioned standard conditions (regarding peak temperature, temperature gradient, temperature profile etc) additional classification and qualification tests have to be agreed upon with Melexis. The application of Wave Soldering for SMD's is allowed only after consulting Melexis regarding assurance of adhesive strength between device and board. Melexis is contributing to global environmental conservation by promoting lead free solutions. For more information on qualification of RoHS compliant products (RoHS = European directive on the Restriction Of the Use of Certain Hazardous Substances) please visit the quality page on our website: http://www.melexis.com/quality_leadfree.aspx
