The TSB81BA3EIPFP from Texas Instruments is an integrated circuit transceiver supporting the IEEE 1394b standard, offering up to 800 Mbits/s data rates. It is designed for high-performance serial bus applications and is fully interoperable with Firewire, i.LINK, and SB1394 implementations.
This transceiver features three backward-compatible, bilingual P1394b cable ports, each capable of operating at up to 800 Mbits/s. It also provides three 1394a-2000 compliant cable ports operating at 100/200/400 Mbits/s. The device supports full 1394a-2000 features, including connection debounce, arbitration acceleration, and extended resume signaling for legacy DV device compatibility.
With a 3V to 3.6V operating voltage and an operating temperature range of -40°C to 85°C, the TSB81BA3EIPFP is suitable for various applications. It is housed in an 80-HTQFP (12x12) package and is designed for surface mount installation. The device includes power-down features and a low-power sleep mode for energy conservation in battery-powered systems.
Key electrical characteristics include a half-duplex operation and support for 6/6 drivers/receivers. The interface to the link-layer controller is pin-selectable for 1394a-2000 or 1394b modes. Fail-safe circuitry is incorporated to sense sudden power loss and disable ports, preventing the device from loading TPBIAS and blocking leakage.
