GPLynx simplifies 1394 implementation

Product Features

• Supports IEEE – 1394-1995 standard (100 and 200 Mbps)
• Compatible with TI’s TSB11LV01/TSB21LV03A PHYs
• 3.3-V operation, 5-V tolerant
• 50 MHz clock frequency
• 50-Quadlet (200 bytes) FIFO
• Characterized for operation from 0°C to 70°C

The TSB12LV31 general purpose link-layer controller merges consumer electronics and computer peripherals by greatly simplifying the implementation of the 1394 high performance serial bus. The TSB12LV31 provides 1394 connection for peripherals with minimum support circuitry.

The device performs bi-directional asynchronous and isochronous data transfers to and from an IEEE-1394 serial bus physical layer device (PHY). Isochronous bandwidth is guaranteed on-demand to specified applications, assuring a constant flow of data for time-critical applications. In addition, an internal 200-byte FIFO is provided on the TSB12LV31 to facilitate asynchronous and isochronous operations.

The TSB12LV31 programmable 8-/16-bit microcontroller interface offers flexibility in selection of the controller. It also features single channel data mover support for isochronous transmit from an unbuffered 8-bit port. The device is tailored and optimized for use as a peripheral link-layer controller (LLC).

Key Applications:

• Digital cameras
• Printers
• Scanners

The TSB12LV31 is available in a 100-pin PZ package (TQFP).
