SMSC Automotive Infotainment
Innovative Customer Solutions Based on Application Knowledge
Semiconductors and IC technology have become ubiquitous
inside of devices we use every day, wherever we work, play,
or travel. To be competitive, semiconductor companies must
continually solve time, space and economic problems for their
customers: do more with less – and do it faster while building
profitability into the value chain.
The real challenge is putting more value into the shrinking real
estate available to semiconductors.

To do that, you have to

know what’s important to your customer and to your customer’s
customers and how to provide it. That is what sets SMSC apart.
Synergy from solving design challenges in multiple, diverse
markets – for example, high-speed computing, connectivity,
embedded networking, consumer electronics and automotive
infotainment applications – enables SMSC to deliver tailored
solutions with lower system costs, so our customers can design
and deliver high-impact products.

Expanding Company & Capabilities
Prior to its 2005 acquisition by SMSC, OASIS SiliconSystems
(OASIS) was one of the largest privately held fabless semi­
conductor companies in Europe, specializing in automotive
infotainment networking technology.
Headquartered in Karlsruhe, Germany, and supported by an IC
engineering team in Austin, Texas, OASIS has built a strong
reputation as a designer of networking solutions for a top tier
customer base of leading automakers and automotive suppliers.
Along with its customers, the company focuses on delivering
IP, silicon, network management software and tools for the
leading standard in automotive multimedia networking: Media
Oriented Systems Transport (MOST), which enables in-vehicle
consumer devices such as DVD players, MP3 players, GPS
systems, car phones and Bluetooth devices, among others, to
work seamlessly as a single system rather than independent
devices each requiring their own control.


To further advance the MOST standard, in 1998, OASIS joined

Integrated Circuits
SMSC’s Automotive Infotainment Systems semiconductor
products are used primarily to connect devices in a network configuration, particularly multimedia networks. Our MOST networking chips enable an interface for optical and electrical physical
layers, multiple speed grades, and sample rates, and connect with
various network types, such as mobile, local, and wireless.
Addressing the harsh environments of the automotive applications, SMSC’s integrated circuits are well suited to satisfy the
stringent quality demands of the world’s largest car manufacturers
and their suppliers.

MOST Network Interface Controllers
Our Network Interface Controllers (NICs) offer a full featured
interface to optical multimedia networks at a bit rate of
25 Mbit/s (MOST25). These controllers perform all relevant
low-level network management including source data allocation,
synchronization, network status detection and physical layer interface operating on chip. The ultra low jitter Phase-Locked
Loop (PLL) guarantees high quality audio/video transmission
and clock recovery over a wide frequency range. On the other
side, standardized interfaces ensure the application’s access.
The MOST interface can be managed by the MOST NetServices,
a software stack that includes the necessary drivers and an
application socket.

The INIC chip family covers MOST Networks with an optical
or electrical physical layer and bit rates of 25 and 50 Mbit/s.
Faster bit rates addressing consumer applications will follow.
All INICs support the new on-PCB and inter-chip communication Media Local Bus (MediaLB™).

MOST Advanced Systems on a Chip
Our complete ‘System on a Chip’ (SoC) semiconductors give
access to all the functionality necessary for multimedia network
applications. The multifunctional hardware platform combines
a microcontroller with flash memory, PLL, DSPs, timers, AD/DA
audio converters and MOST interconnectivity on a single chip.
These SoCs can be programmed for a variety of signal processing solutions like radio, amplifier or active speaker systems.
The respective compilers, assemblers, emulators and simulators
are available to support customer development.

Application Specific Media Processors
Based on our SoC solutions, we provide full featured controllers
programmed by our application experts, including sound and

Tools to Build Your MOST Lab
SMSC’s Automotive Infotainment Systems group offers hardware and software tools that address the entire process chain of
designing, implementing, analyzing and testing MOST Networks
and devices, no matter where the workbench is located: in a
laboratory, on the road or in a production testing environment.
Hardware tools range from PCBs to PC cards and interface
boxes to stand-alone systems.

Software is modular and

supports a variety of needs based on levels of complexity.
SMSC starts by assisting customers in defining MOST multi­
media networks and provides support in simulating, analyzing,
debugging, testing and optimizing the network from trial-anderror to completion. SMSC is the one-stop-solution for com­
patible and upgradeable MOST tools.

PC Interfaces to MOST
MOST PC interfaces focus on simulating MOST devices. They
work as real MOST Network nodes and access all network data.
Hardware and related drivers are available for PC connections.
Software provides easy access and control for device simulation
with components such as MOST Interface Control, MOST NetServices API and MOST Packet Transceiver. Other modules enable customers to visually inspect and analyze network status.
MOST NetServices also allow for the application to be developed
directly on the PC and tested in a realistic MOST Network.
All of SMSC’s MOST development tools can stream real-time
synchronous data to and from a MOST Network.
