Tsi382 PCI Express to PCI Bridge Low Power Consumption The Tsi382A has typical power consumption of less than 0.7W, and it incorporates advanced power management modes to minimize consumption during operation. High Performance In addition to low-latency operation, the Tsi382A’s superior queueing architecture and rich feature set allow designers to optimize their overall system performance. Features such as short-term caching also enable designers to tune the device’s performance for different applications. Transparent and Non-transparent Bridging Transparent mode operation is available for efficient, flow-through configurations, while non-transparent bridging enables multi-host systems and is used in applications such as intelligent adapter cards. Typical Applications The Tsi382A is suited to applications that need to bridge PCIe to downstream PCI devices. Its flexibility, high performance, small footprint, and low power consumption, make it ideal for a range of applications, including:
- Motherboards
- PC adapter cards (communications, graphics, imaging, and multimedia)
- Digital video recorders
- ExpressCards for laptop computers
- Multifunction printers
- Line cards and NICs Motherboard Application 80E2040_TA001_01 PCI 10x10 mm footprint Supports up to four PCI devices off x1 PCIe PCIe Tsi382A PCI Slot PCI Slot Processor Chipset CPU PCIe Slot Peripherals Graphics Memory Other Features
