Functional Blocks
3.4.1
Low Noise Amplifier (LNA)
The LNA is an on-chip cascode amplifier with a voltage gain of 15 dB to 20 dB. The gain figure is determined by
the external matching networks situated ahead of LNA and between the LNA output LNO (Pin 6) and the Mixer
Inputs MI and MIX (Pin 8 and Pin 9). The noise figure of the LNA is approximately 2 dB, the current consumption
is 500 µA. The gain can be reduced by approximately 18 dB. The switching point of this AGC action can be
determined externally by applying a threshold voltage at the THRES pin (Pin 23). This voltage is compared
internally with the received signal (RSSI) level generated by the limiter circuitry. In case that the RSSI level is
higher than the threshold voltage the LNA gain is reduced and vice versa. The threshold voltage can be generated
by attaching a voltage divider between the 3VOUT pin (Pin 24) which provides a temperature stable 3 V output
generated from the internal bandgap voltage and the THRES pin as described in Chapter 4.1. The time constant
of the AGC action can be determined by connecting a capacitor to the TAGC pin (Pin 4) and should be chosen
along with the appropriate threshold voltage according to the intended operating case and interference scenario
to be expected during operation. The optimum choice of AGC time constant and the threshold voltage is described
in Chapter 4.1.
3.4.2
Mixer
The Double Balanced Mixer down-converts the input frequency (RF) in the range of 310 MHz to 350 MHz to the
intermediate frequency (IF) at 10.7 MHz with a voltage gain of approximately 21 dB by utilizing either high- or lowside injection of the local oscillator signal. In case the mixer is interfaced only single-ended, the unused mixer input
has to be tied to ground via a capacitor. The mixer is followed by a low pass filter with a corner frequency of 20 MHz
in order to suppress RF signals to appear at the IF output (IFO pin). The IF output is internally consisting of an
emitter follower that has a source impedance of approximately 330 Ω to facilitate interfacing the pin directly to a
standard 10.7 MHz ceramic filter without additional matching circuitry.
3.4.3
PLL Synthesizer
The Phase Locked Loop synthesizer consists of a VCO, an asynchronous divider chain, a phase detector with
charge pump and a loop filter and is fully implemented on-chip. The VCO is including spiral inductors and varactor
diodes. The FSEL pin (Pin 11) has to be left open. The tuning range of the VCO was designed to guarantee over
production spread and the specified temperature range a receive frequency range between 310 MHz and
350 MHz depending on whether high- or low-side injection of the local oscillator is used. The oscillator signal is
fed both to the synthesizer divider chain and to a divider that is dividing the signal by 2 before it is applied to the
down-converting mixer. Local oscillator high side injection has to be used for receive frequencies between
approximately 310 MHz and 330 MHz, low side injection for receive frequencies between 330 MHz and 350 MHz
- see also Chapter 4.4.
3.4.4
Crystal Oscillator
The on-chip crystal oscillator circuitry allows for utilization of quartzes both in the 5 MHz and 10 MHz range as the
overall division ratio of the PLL can be switched between 64 and 128 via the CSEL (Pin 16) pin according to the
following table.

TDA 5201
ASK Single Conversion Receiver
Functional Description
The calculation of the value of the necessary quartz load capacitance is shown in Chapter 4.3, the quartz
frequency calculation is explained in Chapter 4.4.
3.4.5
Limiter
The Limiter is an AC coupled multistage amplifier with a cumulative gain of approximately 80 dB that has a
bandpass-characteristic centered around 10.7 MHz. It has an input impedance of 330 Ω to allow for easy
interfacing to a 10.7 MHz ceramic IF filter. The limiter circuit acts as a Receive Signal Strength Indicator (RSSI)
generator, which produces a DC voltage that is directly proportional to the input signal level as can be seen in
Figure 6. This signal is used to demodulate the ASK receive signal in the subsequent baseband circuitry and to
turn down the LNA gain by approximately 18 dB in case the input signal strength is too strong as described in
Chapter 3.4.1 and Chapter 4.1.
3.4.6
Data Filter
The data filter comprises an OP-Amp with a bandwidth of 100 kHz used as a voltage follower and two 100 kΩ onchip resistors. Along with two external capacitors a 2nd order Sallen-Key low pass filter is formed. The selection of
the capacitor values is described in Chapter 4.2.
3.4.7
Data Slicer
The data slicer is a fast comparator with a bandwidth of 100 kHz. This allows for a maximum receive data rate of
approximately 120 kBaud. The maximum achievable data rate also depends on the IF Filter bandwidth and the
local oscillator tolerance values. Both inputs are accessible. The output delivers a digital data signal (CMOS-like
levels) for the detector. The self-adjusting threshold on pin 20 is generated by RC-term or peak detector
depending on the baseband coding scheme. The data slicer threshold generation alternatives are described in
more detail in Chapter 4.5.
3.4.8
Peak Detector
The peak detector generates a DC voltage which is proportional to the peak value of the receive data signal. An
external RC network is necessary. The output can be used as an indicator for the signal strength and also as a
reference for the data slicer. The maximum output current is 500 µA.
3.4.9
Bandgap Reference Circuitry
A Bandgap Reference Circuit provides a temperature stable reference voltage for the device. A power down mode
is available to switch off all sub-circuits which is controlled by the PWDN pin (Pin 27) as shown in the following
table. The supply current drawn in this case is typically 50 nA.

LNA Automatic Gain Control Circuitry
The LNA automatic gain control circuitry consists of an operational transimpedance amplifier that is used to
compare the received signal strength signal (RSSI) generated by the Limiter with an externally provided threshold
voltage Uthres. As shown in the following figure the threshold voltage can have any value between approximately
typically 0.8 V and 2.8 V to provide a switching point within the receive signal dynamic range.
This voltage Uthres is applied to the THRES pin (Pin 23). The threshold voltage can be generated by attaching a
voltage divider between the 3VOUT pin (Pin 24) which provides a temperature stable 3 V output generated from
the internal bandgap voltage and the THRES pin. If the RSSI level generated by the Limiter is higher than Uthres,
the OTA generates a positive current Iload. This yields a voltage rise on the TAGC pin (Pin 4). Otherwise, the OTA
generates a negative current. These currents do not have the same values in order to achieve a fast-attack and
slow-release action of the AGC and are used to charge an external capacitor which finally generates the LNA gain
control voltage.

Typical Curve of RSSI Level and Permissive AGC Threshold Levels
The switching point should be chosen according to the intended operating scenario. The determination of the
optimum point is described in the accompanying Application Note, a threshold voltage level of 1.8 V is apparently
a viable choice. It should be noted that the output of the 3VOUT pin is capable of driving up to 50 µA, but that the
THRES pin input current is only in the region of 40 nA. As the current drawn out of the 3VOUT pin is directly related
to the receiver power consumption, the power divider resistors should have high impedance values. R4 can be
chosen as 120 kΩ, R5 as 180 kΩ to yield an overall 3VOUT output current of 10 µA.
Notes
1. To keep the LNA in high gain mode for the complete RF-input level range a voltage equal or higher than 3.3 V
has to be applied at pin 23. Alternatively, pin 23 has to be connected to pin 24 and pin 4 has to be connected
to GND. In addition this would save an external capacitor.
2. To keep the LNA in low gain mode for the complete RF-input level range a voltage lower than 0.7 V has to be
applied to the THRES pin (e.g. THRES connected to GND). In the above-mentioned mode pin 4 has to be
connected by a capacitor to GND.
3. As stated above, the gain control voltage of the LNA is generated at the capacitor connected to the TAGC pin
by the charging and discharging currents of the OTA. Consequently this capacitor is responsible for the AGC
time constant. As the charging and discharging currents are not equal two different time constants will result.
The time constant corresponding to the charging process of the capacitor shall be chosen according to the
data rate. According to measurements performed at Infineon the capacitor value should be greater than 47 nF.

Quartz Load Capacitance Calculation
The value of the capacitor necessary to achieve that the quartz oscillator is operating at the intended frequency is

by the quartz specifications given by the quartz manufacturer.

These values may be obtained by putting two capacitors in series to the quartz, such as 18 pF and 22 pF in the
5.1 MHz case and 18 pF and 12 pF in the 10.2 MHz case.
But please note that the calculated value of CS includes the parasitic capacitors also.

Quartz Frequency Calculation
As described in Chapter 3.4.3, the operating range of the on-chip VCO is wide enough to guarantee a receive
frequency range between 310 MHz and 350 MHz. The VCO signal is divided by 2 before applied to the mixer .
This local oscillator signal can be used to down-convert the RF signals both with high- or low-side injection at the
mixer. High-side injection of the local oscillator has to be used for receive frequencies between 310 MHz and 330
MHz. In this case the local oscillator frequency is calculated by adding the IF frequency (10.7 MHz) to the RF
frequency.
Low-side injection has to be used for receive frequencies between 330 MHz and 350 MHz. The local oscillator
frequency is calculated by subtracting the IF frequency (10.7 MHz) from the RF frequency then. The overall
division ratios in the PLL are 64 or 32 depending on whether the CSEL-pin is left open or tied to ground.
Therefore, the quartz frequency may be calculated by using the following formula:
f QU =
f RF − 10.7

Example
Addition of 10.7 is used in case of operation the device at 315 MHz, subtraction in case of operation at 345 MHz
for instance. This yields the following frequencies:
CSEL tied to GND:
f QU = (315 MHz + 10 .7 MHz ) / 32 = 10 .1781 MHz
(6)
f QU = (345 MHz − 10 .7 MHz ) / 32 = 10 .4469 MHz
(7)
CSEL open:
f QU = (315MHz + 10.7 MHz ) / 64 = 5.0891 MHz
(8)
f QU = (345 MHz − 10 .7 MHz ) / 64 = 5 .2234 MHz

Data Slicer Threshold Generation
The threshold of the data slicer especially for a coding scheme without DC-content, can be generated in two ways,
depending on the signal coding scheme used. In case of a signal coding scheme without DC content such as
Manchester coding the threshold can be generated using an external RC-Integrator as shown in Figure 9. The
time constant TA of the RC-Integrator has to be significantly larger than the longest period of no signal change TL
within the data sequence. In order to keep distortion low, the minimum value for R is 20 kΩ.
