DESCRIPTION
The TSB82AA2B OHCI-Lynx™ Controller is a discrete 1394b link-layer device, which has been designed to
meet the demanding requirements of today’s 1394 bus designs. The TSB82AA2B device is capable of
exceptional 800M bits/s performance; thus, providing the throughput and bandwidth to move data efficiently and
quickly between the PCI and 1394 buses. The TSB82AA2B device also provides outstanding ultra-low power
operation and intelligent power management capabilities. The device provides the IEEE 1394 link function and is
compatible with 100M bits/s, 200M bits/s, 400M bits/s, and 800M bits/s serial bus data rates.
The TSB82AA2B improved throughput and increased bandwidth make it ideal for today’s high-end PCs and
open the door for the development of S800 RAID- and SAN-based peripherals.
The TSB82AA2B OHCI-Lynx Controller operates as the interface between a 33-MHz/64-bit or 33-MHz/32-bit PCI
local bus and a compatible 1394b PHY-layer device (such as the TSB81BA3 device) that is capable of
supporting serial data rates at 98.304M, 196.608M, 393.216M, or 786.432M bits/s (referred to as S100, S200,
S400, or S800 speeds, respectively). When acting as a PCI bus master, the TSB82AA2B device is capable of
multiple cacheline bursts of data, which can transfer at 264M bytes/s for 64-bit transfers or 132M bytes/s for
32-bit transfers after connecting to the memory controller.
