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.

Operating mode => Init Polling TX-Mode RX-Mode active sleep XTO Oscillator (fXTO=24,2879MHz) off on off on on FRC Oscillator (fFRC=6.36MHz) on on off on on SRC Oscillator (fSRC=125kHz) off off on off off 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.
