Theory of Operation
1.1
General
The MLX71122 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). The PLL synthesizer consists of an integrated voltage-controlled oscillator
with external inductor, a programmable feedback divider chain, a programmable reference divider, a phasefrequency detector with a charge pump and an external loop filter.
In the receiver’s down-conversion chain, two mixers MIX1 and MIX2 are driven by the internal local oscillator
signals LO1 and LO2, respectively. The second mixer MIX2 is an image-reject mixer. As the first intermediate frequency (IF1) is very high (typically above 100 MHz), 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 receiver signal chain is setup by a low noise amplifier (LNA), two down-conversion mixers (MIX1 and
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+/-).
In general the MLX71122 can be set to shut-down mode, where all receiver functions are completely turned
off, and to several other operating modes. There are two global operating modes that are selectable via the
logic level at pin SPISEL:
•
•

P
8-channel preconfigured mode (ABC mode)
fully programmable mode (SPI mode).
In ABC mode the number of frequency channels is limited to eight but no microcontroller programming is
required. In this case the three lines of the serial programming interface (SPI) are used to select one of the
eight predefined frequency channels via simple 3-bit parallel programming. Pins ENRX and MODSEL are
used to enable/disable the receiver and to select FSK or ASK demodulation, respectively.
SPI mode is recommended for full programming flexibility. In this case the three lines of the SPI are configured as a standard 3-wire bus (SDEN, SDTA and SCLK). This allows changing many parameters of the
receiver, for example more operating modes, channels, frequency resolutions, gains, demodulation types,
data slicer settings and more. The pin MODSEL has no effect in this mode.

As all pins, pins A, B, and C are equipped with ESD protection diodes that are tied to VCC and to VEE.
Therefore these pins should not be directly connected to positive supply (a logic “1”) before the supply voltage is applied to the IC. Otherwise the IC will be supplied through these control lines and it may enter into an
unpredictable mode. In case the user wants to apply a positive supply voltage to these pins before the supply voltage is applied to the IC, a protection resistor should be inserted in each control line.

Functional Description
2.1
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:
•
•
•
•
receiving at fRF(high-high)
receiving at fRF(high-low)
receiving at fRF(low-high)
receiving at fRF(low-low)
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:
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).

300 to 930MHz Receiver
Evaluation Board Description
Due to the double superhet receiver architecture, the channel frequency step size fCH is not equal to the
phase-frequency detector (PFD) frequency fPFD. For high-side injection, the channel step size fCH is given by:
f CH =
f RO N LO2 − 1
N −1
= f PFD LO2
R N LO2
N LO2

While the following equation is valid for low-side injection:
f CH =

f RO N LO2 + 1
N +1
= f PFD LO2
R N LO2
N LO2
(4)
Calculation of Counter Settings
Frequency planning and the selection of the MLX71122’s PLL counter settings are straightforward and can
be laid out on the following procedure.
Usually the receive frequency fRF and the channel step size fCH are given by system requirements. The N
and A counter settings can be derived from Ntot or fLO1 and fPFD by using the following equations.
N = floor(

Calculation of LO1 and IF1 frequency for Low Frequency Bands
High-high injection must be used for the low frequency bands. First of all choose a PFD frequency fPFD
according to below table. The R counter values are valid for a 10MHz crystal reference frequency fRO. The
PFD frequency is given by fPFD = fRO /R.

The second step is to calculate the missing parameters fLO1, fIF1, Ntot, N and A. While the second IF (fIF2), the
NLO2 divider ratio and the prescaler divider ratio P are bound to fIF2 = 2MHz, NLO2 = 4 (or 8) and P =32.

PLL Counter Ranges
In order to cover the frequency range of about 300 to 930MHz the following counter values are implemented
in the receiver:
PLL Counter Ranges
A
N
R
P
0 to 31 (5bit)
3 to 2047 (11bit)
3 to 2047 (11bit)
32
Therefore the minimum and maximum divider ratios of the PLL feedback divider are given by:
N totmin = 32 ⋅ 32 = 1024
2.3
2.3.1
N totmax = 2047 ⋅ 32 + 31 = 65535
SPI Description
General
Serial programming interface (SPI) mode can be activated by choosing SPISEL = 1 (e.g. at positive supply
voltage VCC). In this mode, the input pins 17, 18 and 19 are used as a 3-wire unidirectional serial bus interface (SDEN, SDTA, SCLK). The internal latches contain all user programmable variables including counter
settings, mode bits etc.

A
N

M

L
E
R
P
In addition the MFO pin can be programmed as an output (see section 4.1.4) in order to read data from the
internal latches and it can be used as an output for different test modes as well.
At each rising edge of the SCLK signal, the logic value at the SDTA terminal is written into a shift register.
The programming information is taken over into internal latches with the rising edge of SDEN. Additional
leading bits are ignored, only the last bits are serially clocked into the shift register. A normal write operation
shifts 16 bits into the SPI, a normal read operation shifts 4 bits into the SPI and reads additional 12 bits from
the MFO pin. If less than 12 data bits are shifted into SDTA during the write operation then the control register may contain invalid information.
In general a control word has the following format. Bit 0 is the Read/Write bit that determines whether it is a
read (R/W = 1) or a write (R/W = 0) sequence. The R/W bit is preceding the latch address and the
corresponding data bits.

Mode

There are two control word formats for read and for write operation. Data bits are only needed in write mode.
Read operations require only a latch address and a R/W bit.
Due to the static CMOS design, the serial interface consumes virtually no current. The SPI is a fully separate
building block and can therefore be programmed in every operational mode.
