2010 JAGUAR XFR Module

7 Triple TV antenna module 8 RF filter The diversity antenna module, located on the left hand side of the heated rear window, receives signals from four antennas
located in the heated rear window, where one antenna is dedicated as an AM antenna.

The diversity tuning system ensures that the strongest signals are used by the radio system to ensure the best possible FM
reception. Using the three remaining receiving antennas serves to eliminate multipath signal distortion. Typically, the signal
from the antenna with the least noise is chosen, and the other antennas are ignored.

The diversity antenna module is an interface between the antenna aerials in the heated rear window and audio system
modules/tuners. It provides antenna signals to the AM/FM tuner in the IAM, to the DAB receiver and to the VICS (vehicle
information and communication systems) or TMC (traffic message channel) in the navigation computer.

There are three different types of diversity antenna module fitted depending on the vehicle market and infotainment
equipment specification:
AM/FM with one co-axial output
AM/FM and VICS/TMC with two co-axial outputs
AM/FM, VICS/TMC and DAB band III with three co-axial outputs
The diversity antenna module receives a power supply from the IAM.

Vehicle or other component generated electromagnetic interference may cause unwanted disturbances in the radio and TV
reception signals. The disturbance may interrupt, obstruct, or otherwise degrade or limit the effective performance of the
circuit. It frequently affects the reception of AM radio in urban areas and can also affect FM radio and television reception,
although to a lesser extent.

The RF filters, which act as RF isolators, are located on both sides of the heated rear window and are used to reduce the
electromagnetic interference. The left hand side RF filter is connected across the heated rear window power supply and used to
separate the DC (direct current) interference from the RF signals. The right hand side RF filter is used in conjunction with the
TV antenna module (if fitted). If the TV system is not fitted the filter is linked directly to ground.

INFORMATION CONTROL MODULE



The ICM is located beneath the IAM in the center console. The unit performs a range of infotainment and some climate-control
functions.

The ICM, which is the timing master of the MOST system; supplies clock information to all other devices on the network which
synchronize their operation to this clock.

The unit also controls and manages the MOST ring and provides the allocations of channels, system power management,
functionality and co-ordination of the other system components.

The system becomes operational when the vehicle is unlocked and a 'wake up' signal is received by the ICM on the medium
speed CAN. The ICM 'wakes up' all the control modules on the MOST system ready for immediate operation by the vehicle user. If the ICM is replaced it must be configured as a new module using the Jaguar approved diagnostic equipment.

Calibration of the ICM using the Jaguar approved diagnostic equipment enables updates to be downloaded as new technology
becomes available or any fault concerns require software updates.

PORTABLE AUDIO MODULE

controlled through the device itself.


NOTE: The system will support devices with a storage capacity up to 256 GB which is approximately 65,000 audio tracks.

The wiring link harness between the portable audio module and interface panel consists of hardwired and digital connections
for data and signal exchange. The MOST carries the communication signals and information between the portable audio module
to the IAM and touch-screen. Audio output to the speaker system is controlled by the IAM or power amplifier depending on the
audio system specification.

POWER AMPLIFIER


The audio system has three amplification options dependant on the audio system specification:
IAM internal amplifier
Alpine AUD 8
Alpine AUD 12

The power amplifier is located in the left hand side of the luggage compartment and is connected to the audio system via the
MOST bus. Speaker connections are hardwired.
If the power amplifier is replaced it must be configured as a new module using the Jaguar diagnostic equipment.

Calibration of the power amplifier using the Jaguar approved diagnostic equipment enables updates to be downloaded as new
technology becomes available or any fault concerns require software updates.

DIGITAL AUDIO BROADCASTING

DAB is a digital radio network designed to provide reliable, multi-service broadcasting for reception by mobile, portable and
fixed receivers.

DAB provides a clear signal with minimal interference, hiss or fading. After a channel (or station) has been tuned and stored, it
does not need retuning.


NOTE: Radio signals travel in a straight line so large obstacles, such as tall buildings, can shield the vehicle from the
signal causing temporary loss of reception (known as dead spots).

Digital radio is transmitted from regional terrestrial transmitters. Some local digital radio channels are not available outside
the range of a transmitter. To receive new local channels during vehicle movement around a country, the auto-tune function is
used to build new channel lists.

NOTE: When the vehicle DAB radio is first used the system will not receive any digital stations until the auto-tune
function has been completed.

Digital radio channels are organized into groups called ensembles (also known as multiplexes). Some individual channels may
also provide a number of subchannels. For example, if several sports events are being held simultaneously, the channel may
temporarily choose to broadcast each different event on a separate subchannel.

DAB is broadcast across Europe, Canada and parts of Asia. System transmission is via a terrestrial network, on two separate
broadcasting bands:

DAB band-L
DAB band III

The DAB system requires additional components to be added to the audio system. DAB antennas and a receiver are fitted to
allow reception of the service.

Operation of the DAB system is the same as the radio operation with selections made through the touch-screen and ICP to
access and navigate the system functions.

The DAB receiver is a dedicated tuner which is controlled by the ICM on the MOST ring. The receiver processes the signals from
the DAB antennas. Information is transmitted on the MOST ring and processed by the ICM. The processed information is sent
out to the power amplifier or IAM (with internal amplifier) and broadcast through the speaker system.

No configuration procedure is required if the DAB receiver is replaced. Calibration of the DAB receiver using the Jaguar
approved diagnostic equipment enables updates to be downloaded as new technology becomes available or any fault concerns
require software updates.
Digital Audio Broadcasting Antennas



Item Description 1 Roof pod 2 Diversity antenna module The DAB band III antenna is located in the heated rear window and is part of the diversity antenna module circuit. The two
antenna circuits each have a co-axial connection to the DAB module.

DAB signals are transmitted on either DAB band III (174 - 240 MHz) or DAB band-L (1452 - 1492 MHz). Some countries may
only use the band III signals, while others may only use the band-L signals. Some countries use both frequency ranges within
the same geographical area. The type of DAB signal received depends on the vehicle market location.

The DAB antennas are designed with 50 ohm output impedance. The DAB receiver is fitted with 50 ohm fakra II connectors to
ensure compatibility with the antenna. For optimum performance 50 ohm low loss coaxial cable is used between the antenna
and receiver.
