1394 Serial Bus Devices
TSB21LV03A
Product Description
The TSB21LV03A is a 3.3V, three port cable transceiver/arbiter that supports cable data transfer rates of 200/100 Mbps. It performs system initialization and arbitration functions, as specified by the IEEE-1394-1995 High Performance Serial Bus Standard.
The TSB21LV03A is designed to interface with a link layer controller (LLC), such as the TSB12LV21 or TSB12LV31. In addition, all Digital I/Os are 5V tolerant. The data interface to the LLC is provided through four parallel lines operating at 50 Mbps.
A cable inactivity monitor output and power down input provide "sleep-mode" power savings.
Target Applications
Host Adapter Cards
The TSB21LV03A, along with a link layer controller (LLC), provides three fully compliant 1394 data ports to a PC or Workstation platform. Evaluation Module (EVM) kits are available from TI that can be used as a starting point for adapter card design.
Motherboards
The TSB21LV03A enables a motherboard manufacturer to add up to three 1394 connections without taking up valuable motherboard real-estate.
High Speed Peripheral Devices
The TSB21LV03A provides a way to add 1394 connections to any high speed digital device requiring up to three 1394 cable ports. Evaluation Module (EVM) kits are available from TI that can be used as a starting point for peripheral design.
