Tsi574™
4/8 SERIAL RAPIDIO SWITCH
The Tundra Semiconductor Corporation (Tundra) Tsi574TM is a third
generation RapidIO switch supporting 40 Gbits/s aggregate bandwidth. The
Tsi574 is part of a family of switches that enable customers to develop
systems with robust features and high performance at low cost.
Features
Serial RapdIO Interfaces
• 40 Gbits/s Full-Duplex Serial RapidIO Switch
• Open Standard Compliant
– RapidIO Interconnect Specification
(Revision 1.3)
The Tsi574 provides designers and architects with maximum scalability to
design the device into a wide range of applications. Flexible port
configurations can be selected through multiple port width and frequency
options.
Building on the industry leading Tsi564ATM 4/8 Port Serial RapidIO Switch,
the Tsi574 contains all the benefits of its predecessor plus enhances the
fabric switching capabilities through the addition of multicast, traffic
management through scheduling algorithms, programmable buffer depth,
and fabric performance monitoring to supervise and manage traffic flow.

• Programmable buffer management
• Additional scheduling algorithms
Embedded applications further benefit from the ability to route packets to
multiple endpoints through hierarchical lookup tables, independent unicast
and multicast routing mechanisms, and error management extensions that
provide proactive issue notification to the fabric controller. In addition, the
Tsi574 supports both in-band serial RapidIO access and out-of-band access
to the full fabric register set through the I2C interface.
Low Power
• Programmable SerDes
• Configurable on port width and speed
• Configurable port power down
• Further power savings from Tsi564A
Cost
