TSB12LV01B

The TSB12LV01B from Texas Instruments is a high-performance IEEE 1394-1995 standard compliant link-layer controller designed for easy integration into I/O subsystems. It facilitates high-speed data transfer between a 32-bit host bus and the 1394 PHY-link interface, supporting asynchronous and isochronous data transfers.

This controller supports transfer speeds of 100, 200, and 400 Mbits/s, correctly formatting and transmitting/receiving 1394 packets. It includes a 32-bit CRC generation and checking capability and can function as the 1394 cycle master. The device features an internal 2K-byte memory that can be configured as multiple variable-size FIFOs, eliminating the need for external FIFO components.

Operating from a 3.3V power supply while maintaining 5V tolerant inputs, the TSB12LV01B is manufactured using low-power CMOS technology. It is available in a 100-pin PZT package, suitable for industrial applications with operating temperature ranges from 0°C to 70°C and -40°C to 85°C.

Key features include a generic 32-bit host bus interface, interrupt-driven operation to minimize host polling, and compatibility with Texas Instruments physical layer devices (PHYs).
