An integrated circuit contains the complete transceiver and antenna switch. The received signal is matched to the an LNA input, demodulated and transmitted via a digital interface to the ECU. The implemented µC configures PLL and the RF-frontend to create an output signal and sets the antenna switch according to the receive/transmit mode. Received or transmitted signal is limited in bandwidth by a SAW filter. Both use the same antenna. 4.3 Installation The remote control box is installed inside a vehicle and behind the cabin cover. Only service personel is able to touch or handle it. 4.4 Operating temperature range -40 … +85°C

Printed versions and local copies are not maintained by change management 5.5 Frequency creation and Frequency 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. 5.6 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. 5.7 ON / OFF State of Oscillators in dependency of operating mode • Polling cycle time : 50ms • active (without signal): tAKTIV= 3.05ms (typ.) • Sleep-phase: tSleep=46.95ms (typ.)
