Applications
Distributed Isochronous Network
Low latency isochronous backbones provide for the
deployment of systems that require cost effective
implementation, high bandwidth, predictable data
transfer delays and direct synchronization with the
wide area network.
Some
Integration (CTI) require a large amount of
bandwidth to be transported between multiple
chassis within the same location, or between
separate locations. The MT90840 is ideal for
implementing physically distributed transport and
switching systems for multi-chassis or inter-shelf
communications.
applications
in
Computer
Telephony
The MT90840 bridges existing Zarlink ST-BUS
components into a new networking environment
where mixed data, voice and video signals can be
time-interchanged or multiplexed from serial PCM
streams
onto
serial
high-speed
multiplex (TDM) isochronous backbones operating at
time-division-
SONET rates such as 51 (STS-1) or 155 Mbps
(STS-3).
Today, transmission links operating at SONET rates
utilize
serial-to-parallel
converters (or framers) which perform embedded
framing functions and give the user access to the
payload of the high speed frame. The MT90840
provides an 8-bit bidirectional parallel data port
which directly interfaces to a high-speed framer
parallel data interface, allowing designers to build
distributed networking systems with interconnection
speeds up to 155 Mbps. Figure 16 shows an
example of a distributed networking application in a
CTI system.
and
parallel-to-serial
The MT90840's clock synchronization and reference
options allow many applications and topologies
when isochronous TDM backbones are required.
Two major clock synchronization schemes provided
by the MT90840 allow the serial port interface
(ST-BUS) to provide the master clock and frame
reference signals for the distributed high speed
backbone (master operation) or to derive the entire
ST-BUS clock and frame reference signals from the
high speed backbone (slave operation). This type of
