说明
The TSB83AA23 is an integrated IEEE Std 1394b-2002 link-layer controller (LLC) design and physical layer (PHY) design combined in a single package to meet the demanding requirements of today’s 1394 bus applications. The TSB83AA23 device is capable of exceptional 800-Mbps performance; thus, providing the throughput and bandwidth to move data efficiently and quickly between the PCI and 1394 buses. The TSB83AA23 device also provides outstanding ultralow power operation and intelligent power-management capabilities. The device provides the IEEE 1394 LLC function and PHY function and is compatible with 100-Mbps, 200-Mbps, 400-Mbps, and 800-Mbps serial-bus data rates.
The TSB83AA23 operates as the interface between 33-MHz/32-bit PCI local bus and an IEEE Std 1394a-2000 or IEEE Std 1394b-2002 serial-bus interface.
