GPLynx - TSB12LV31

Product Description

The TSB12LV31 was designed specifically for 1394 computer peripheral applications and is tailored and optimized for use as a "peripheral" link layer controller. It performs bi-directional asynchronous/ isochronous (ISO) data transfers to and from an IEEE-1394 serial bus physical layer device (PHY). It is referred to as GPLynx, short for "general purpose link".

The TSB12LV31 provides 1394 connection for peripherals with a minimum of support circuity. The programmable microcontroller interface provides customer flexibility in selection of the controller, which may already exist in the current product design. Unlike its predecessors, the TSB12LV31 has a programmable 8/16-bit data bus interface to the selected microcontroller. Also, single channel data mover (DM) support is provided for unbuffered ISO transmit to the unbuffered 8-bit ISO port.

With the release of this product, TI remains the leading supplier of IEEE-1394 silicon on the market and the leader in total 1394 solutions including silicon, software, and evaluation modules.

Target Applications

  • Digital Cameras

    The TSB12LV31 Link Layer Controller (LLC) guarantees bandwidth up to 200 megabits/second for uncompressed, full-motion, real-time color video. Asynchronous mode can be used for camera controls.

  • Printers

    The TSB12LV31 LLC allows high-end printers that require data rates in excess of 8 Mbps an upgrade path from existing SCSI.

  • Scanners

    The TSB12LV31 LLC accomodates scanner data rates, which are bursty, with ample bandwidth so that memory requirements may be reduced.
