The Texas Instruments TSB81BA3 is a high-performance controller for IEEE 1394b and 1394a serial bus standards. It fully supports provisions of IEEE P1394b Revision 1.33+ at 1-Gigabit signaling rates and IEEE 1394a−2000 and 1394−1995 standards.
This controller provides three fully backward-compatible, bilingual P1394b cable ports capable of up to 800 Megabits per second (Mbits/s). Additionally, it offers three 1394a−2000 fully compliant cable ports operating at 100/200/400 Mbits/s. Key features include connection debounce, arbitrated short reset, multispeed concatenation, arbitration acceleration, fly-by concatenation, and port disable/suspend/resume functionality.
Designed for energy conservation, the TSB81BA3 includes power-down features and a low-power sleep mode, making it suitable for battery-powered applications. It also supports Open Host Controller Interface (HCI) requirements and features cable power presence monitoring. The device is available in LQFP or MicroStar BGA packages.
The TSB81BA3 operates from a single 3.3V supply with a 1.8V internal core voltage.
The TSB81BA3 is available in a 144-pin LQFP (22mm x 22mm) and a 176-pin MicroStar BGA package.
The operating temperature range is -40°C to 85°C.
The TSB81BA3 supports serial bus data rates of 100 Mbits/s, 200 Mbits/s, 400 Mbits/s, and 800 Mbits/s.
It provides three fully backward compatible bilingual P1394b cable ports at up to 800 Mbits/s and three 1394a-2000 compliant cable ports at 100/200/400 Mbits/s.
Yes, it is fully interoperable with Firewire, i.LINK, and SB1394 implementations of IEEE Std 1394.
Yes, it supports D0, D1, D2, and D3 power states and PME events per the PCI Bus Power Management Interface Specification.
