3.4.2 Modulation
Frequency modulation FSK with 10kHz deviation.
3.4.3 Channel definition
The following table shows the center-frequencies for each channel.
The frequency-separation between two adjacent channels is 450 kHz.
Channel name Center-frequency
name Short name
channel 1 CH1 ECE: 433,47 MHz
channel 2 CH2 ECE: 434,37 MHz
channel 3 CH3 ECE: 433,92 MHz
table 1: center frequencies of all channels
3.4.4 Carrier frequency
The carrier frequency has a tolerance (including influences because of temperature,
aging, manufacturing tolerance) of:
ECE: 433,47 MHz 70ppm, 433,92 MHz 70ppm, 434,47 MHz 70ppm
3.5 Frequency Generation and Stability
The RF-frequencies are created with a fractional N PLL (phase locked loop). The frequency of
the local oscillator is controlled by the fractional N Synthesizer. The discrete channel-
frequencies are configured by digital settings
The RX and TX- frequency deviation is ±10 kHz
The RX intermediate frequency (IF) is 250kHz.
RX receiver channel bandwidth is 165kHz.
The PLL is referenced to a crystal oscillator
The crystal oscillator (XTO) is operated at fXTO = 24,2879 MHz
The tolerance of the crystal is ±70ppm.
3.6 Further signal-sources (clock generators):
Slow RC Oscillator: fSRC=125kHz ±5% Sleep Time reference in polling mode.
Fast RC Oscillator: fFRC=6.36MHz±10% System clock reference CPU.

4 Operational Procedures
After connecting supply voltage, the module is NOT in normal operating mode.
To get the module into normal operating mode (polling mode):
Connect supply voltage (12V) and GND
Pull the data line to GND for a short time (>5ms)
5 Certification
USA
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesired operation.
