4 Overview
4.1 Block diagram
Figure 1: Blockdiagram of the remote control circuit
4.2 Functional description
The RF-Signal is received/transmitted by the integrated antenna and is filtered by a bandpass.
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

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.)

6 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)
