The Digital Data Bus (D2B) is a
networking protocol for automotive
multimedia
data
communication
integrating digital audio, video and
other high data rate synchronous or
asynchronous
signals,
with
the
control
data
for
network
management protocols and APIs.
The protocol enables robust single
cable
interconnection
and
compatible interoperation of in-car
AV multimedia and ITS devices, such
as Radio Head Units, CD Changer,
CD-ROM, GPS Navigation, Voice
Control, Car Telephones, TV
and
others.

- OCC8001-02
The OCC8001-02 transceiver is a pin
compatible
successor
of
the
OCC8001-01
with
identical
functionality,
featuring
decreased
power and reduced EMI
The CONAN
is an advanced CMOS
device
which
enhances
network
design by integrating source data
routing and communication protocol
management.

Device control is handled via the
control
port,
which
can
be
configured as either an I2C or SPI
compliant interface. The choice of
interface is specified during hardware
resets.

Data is organized in frames which are
transmitted at the system sampling
frequency. Frames contain source
and
control
information
and
are
further divided into sub-frames of 8
bytes fields. At the physical level, data
is transferred as serial bits with bi-
phase encoding.
Fully compliant with D2B Mode0

Control data is constructed into a
control frame, which is transferred at
a rate of two bits per sub-frame. The
control frame comprises 128 bits
and requires a block of 48 frames to
transmit.

Six source data ports are provided,
giving the flexibility for multiple data
sources and destinations to be
handled by a single CONAN
.
All data ports share a common frame
synchronization and serial bit clock.
Data can be arranged as Philips I2S,
Sony or Matsushita, 16 or 24 bit serial
formats. Additionally, SR0 and SX0 can
be configured for operation as an
IEC-958 (or SPDIF) interface. Source
and
destination
data
is
routed
between the source data ports and
the network interface via the Routing
Information Table. This allows all data
bytes coming from either the network
receiver or source input ports to be re-
arranged, mixed and re-directed to
the network transmitter or source
output ports.
