Tsi384™
PCI Express to PCI/X Bridge
The Tundra Semiconductor Tsi384 is a high-performance bus bridge that
connects the PCI Express (PCIe) protocol to the PCI and PCI-X bus standards.
Features
General
• PCI Express to PCI/PCI-X Forward bridge
• Transparent, Non-transparent, and
Opaque modes
• Low latency – Superior queuing and
buffering architecture maximize
throughput and minimize latency
The Tsi384’s PCIe Interface has superior performance and supports 1, 2, or 4
lanes. This enables the bridge to offer exceptional throughput performance
of up to 1 GBps.
The device’s PCI/X Interface can operate up to 133 MHz in PCI-X mode, or up
to 66 MHz in PCI mode. This interface offers designers extensive flexibility by
supporting three types of addressing modes: transparent, opaque, and
non-transparent.
• Compliant with the following
specifications:

80E1000_BK001_01 (Tsi384)
• 32/64-bit addressing
• 32/64-bit data
• PCI-X operation at 50, 66, 100, and
133 MHz
• PCI operation at 25, 33, 50, and
66 MHz
• Up to eight outstanding memory reads
• 4K read completion buffer
Low Power Consumption
The Tsi384 has typical power consumption of 1.3W, and incorporates
advanced power management to minimize power consumption during
operation. In addition to supporting D0, D3 hot, and D3 cold power
management modes, the device permits unused PCIe lanes to be powered
off automatically or by configuration.
• Four external PCI/X masters supported
through internal arbiter
• Support for external arbiter
• 3.3V PCI/X I/Os

Tsi384
Transparent, Non-transparent, and Opaque Bridging
Other Features
Transparent mode operation is available for efficient, flow-through
configurations, while non-transparent bridging allows isolation between the
Tsi384’s PCIe and the PCI/X domains. Non-transparent bridging also enables
multi-host systems and is used in applications such as storage adapters.
Opaque mode provides semi-transparent operation for multi-processor
configurations and enhanced private device support.
• Support for Masquerade mode
• JTAG IEEE 1149.1, 1149.6
• Support for D0, D3 hot, D3 cold power
management states
• 1.2V core power supply
• 1.3W typical power consumption
(x4 PCIe to 133-MHz PCI-X)
High Performance
The Tsi384 incorporates many advanced PCIe protocols that increase system
performance, including: Lane Reversal and Polarity Inversion, end-to-end
CRC, ASPM L0 link state power management, and Hot Plug. In addition to
low-latency operation, the device supports a maximum payload size of up to
512 bytes to allow better throughput efficiency.
• Packaged in 17x17 mm, 256-pin PBGA
• Package pinout and footprint
compatible with PLX8114
Benefits
• Enhances system performance by
delivering high throughput and low
latency across bus interfaces
• Simplifies system design by offering
numerous programmable features
• Minimizes system power consumption
by providing comprehensive power
management
Typical Applications
The Tsi384 is suited to applications that need to bridge from PCIe to
downstream PCI-X and PCI devices. Its flexibility, high performance, small
footprint, and low power consumption, make it ideal for a wide range of
applications, including:
• Storage Area Network (SAN, RAID HBA cards)
• Network Attached Storage, Direct Attached Storage (NAS, DAS)
• Line cards and NICs
Design Support Tools
• Routers and switches
• Motherboards (server, SBC, industrial PC)
• PC adapter cards (communications, graphics, imaging, and multimedia)
• Multi-function printers
